okay so M andami and M
okay got it
you are the winner of today's session got
worry got
Time intro okay let me tell you a intro
about myself okay this is me Anish
masters of chemistry okay from nit Jal
and expert in neat and J Main and just a
mentor that's it okay so that's
okay
yes sir it is important for NE yes of
chapter but don't no need to worry about
anything okay because I'm here okay got
it so now here
reaction in the explain first L of
el g r okay
sorry l e g e okay
examp it means loss of electron okay so
Okay g e gain of electron oh g e r got
it
forget rule
[Music] so
this is your task number
one so that's it my dear friends okay so
electrochemistry okay so
n shock homes Ain yes first one

so
okay just okay so please let me know in
the chat box my dear friends that's it
simple ELR electrochemical cell that's
it that's it that's it so negative positive
okay okay so next um cell reaction first
an plus two electron that's it okay next at
2 chemical reaction
reaction
okay okay reaction representation
oxidation next reduction
right solid so Z 2 plus aqu copper
zinc okay so now here copper 2 plus right
right
copper copper 2 plus aqu
reduction copper that's
okay okay you don't need to worry about
anything yes my dear
bridge
salt bridge so the salt
bridge it's a
polysaccharide polysaccharide okay so in the
the
poly sometimes in electrolyte so polyc
Electro electrolyte
electrolyte
Electro like K3 pottassium nitrate okay
potassium nitrate
Mobility got
[Music]
okayge okay and sometimes
sometimes but
but
any next to minimize liquid liquid Junction
potential
AG okay gg3 next TL kalium next PB and Mercury
yes
trick okay AIT y power hero okay he is a
power star power hero
here silver next
next Mercury that's it yes or no my dear
it
here
oxidation C oxidation half cell okay
cell the solution
Neti so posi potential negative potential
junctional okay that's it so this is our
liquid liquid Junction
potential got it yes or no my dear
friends that's it so
all metal 2 plus or metal plus oron
positive just positive
okay okay
push
Co 2 plus
and two
El okay oxidation right
copper 2+
plus copper gives copper 2+ plus two elect
okay
so in the electrode potential of
minus e r e d not that's
here
first e not
oxidation okay oxidation of c
c c
O Okay is equal to minus E reduction am
I right okay got it so that's it so minus
minus
codus e not okay that's it so minus
anode plus
e reduction of
e okay
okay EAS e okay and E not
yes what's your doubt please let me know in the chat
box okay
okay so sir e not anode negative sir then it
so sir e not anode negative sir then it will become zero sir e not anode anode
will become zero sir e not anode anode negative it will become
negative it will become zero both are reduction only no sir
1.1 okay the not cell of that reaction copper
the not cell of that reaction copper okay 1.1
okay 1.1 Vol
you have to remember something what was that one bar
that one bar okay one bar okay one bar
pressure 25° or 298 okay 298 K okay then after
25° or 298 okay 298 K okay then after that concentration
okay next cannot
standard reduction potential is more important more important more
standard for
okay top okay top
okay sir is one of the intelligent and more most obedient student in our
more most obedient student in our classroom sir whenever I put any
classroom sir whenever I put any homework she is the one finish it fast
homework she is the one finish it fast oh my God when I'm saying that oh my god
oh my God when I'm saying that oh my god really is it true yes it is true yes it
really is it true yes it is true yes it is true yes I'm so happy about it okay
is true yes I'm so happy about it okay now I'm asking that
because she is okay she is the one completing the homeworks
good Jesus or
good I don't think so you know that I don't think so definit no way no no no
don't think so definit no way no no no no no no no no
no more more intelligent okay so defin so like the
so like the way good or
good yes so like the way
reference okay like the way yes of course especially at
reference s like the way okay so now
s like the way okay so now here okay
okay if there is no she okay there is no without
Platinum gas okay so the
gas okay so the gas keep it in your mind so the
surf chemistry surf chemistry deleted so sad
chemistry surf chemistry deleted so sad okay the
gas this process is not absorption it's it's
absorption and even the metal the platinum
that's because life even she or he both are important
are important okay life
standard one bar pressure and temperature 25° C or 298
temperature 25° C or 298 29
29 25 okay so elect
25 okay so elect potential
Nealy okay so that's it
it reaction stand we know that
reaction stand we know that concentration
got it so here standard reduction

engor got it yes PB is
okay this is our F
F so
so this
yes reduction oxidation which is more important okay so that's more important
important okay so that's more important okay first repeat FB okay
FB chance Paris France Singapore America and
Paris France Singapore America and England okay so this is a
fast so
fast so this is a shortcut my dear friends that's it that's it that's it
and are rich countries okay well developed
countries so they will oxidize they will reduce okay that's it so
SRP value standard reduction
reduction they will reduce fast
man positive so positive so they will reduce
negative got it
s positive positive positive negative so Sr
positive positive negative so Sr positive reduce F
positive reduce F right reduce fast
agent okay so SRP value increases oxidizing
ability oing ability oing

agent ability
that's Reas coer
coer copper copper 2 plus
next AG Plus and AG okay so AG plus
okay aqu
aqu next okay
next okay solid that's
solid that's it copper copper to h plus h so option
it copper copper to h plus h so option three is the right answer that's
it yeah like the way so now here this is
yeah like the way so now here this is the question time this is your task this
the question time this is your task this is your task my dear friends my dear
is your task my dear friends my dear friends make sure
yes this is your homework my dear friends this is your homework okay
M yes I know that without she he is nothing let without she is nothing
of course it's
temp El potential stand so
potential stand so standard
like yeah n RT RT NF
NF rtnf
okay so RTF okay so RT
natural next equation so equation so the next equation gas
equation so the next equation gas constant okay
temp electrol number
electrol number El
far what is the charge of electron my dear friends please let me know in the
dear friends please let me know in the chat box charge of electron
chat box charge of electron Bo what is the charge of electrons
okay magnitude value so okay so charge of one Mo okay one Mo
elect charge of one mole electron one Mo 6.02 into 10 the power 20 23 am I right
6.02 into 10 the power 20 23 am I right got it
got it so 1.6 into
109 96500 okay one Mo just fic meaning okay
wait wait wait okay number
quti reaction Q equal to concentration of product divid by concentration of
of product divid by concentration of reactant okay so normal of red redo
reactant okay so normal of red redo reaction okay so normal redox
reaction okay so normal redox reaction P
equation just Jin copper
Jin copper 2+ solid
2+ solid aqu copper solid plus 2
plus e e not e cell is equal to e not cell
cell is equal to e not cell minus
minus 0.06 divid by n right
minus two okay log concentration of
that reaction okay
reaction okay just got it
okay got it so Z e cell is equal
Z e cell is equal to
to right
okay that's it
simple. it's fine okay so now relationship between Delta G
okay so now relationship between Delta G and E not cell Direct
okay um Delta Gus NF
exam okay so free energy I know
so free energy I know that spontaneous reaction spontaneous
that spontaneous reaction spontaneous reaction free energy okay for the
reaction free energy okay for the spontaneous reaction
soont that's it Point okay so now here in G free energy
property exensive property it means this
quantity like
like cens property it means quality this is
cens property it means quality this is quality so intensive
quality so intensive property okay this is non additive non
ad okay elect
elect cell
cellion you guys are really lucky you know
know that
because this is quantity based this is extensive
property this is intensive property it means
okay it means value okay so now electroly
elro iner
here by using so by using
okay okay so by using electrical energy spontaneous
energy spontaneous reaction made for each
other okay so chemical
okay so chemical energy chemical ener electrolytic okay
energy chemical ener electrolytic okay so
okay so now here electrolytic
electricity okay so keep it in your mind so electrolytics electricity okay so now
so electrolytics electricity okay so now here anod
that's it okay
[Music] so like yeah just leave it
so like yeah just leave it okay so now here
okay so now here so that's
C opposite charge attract okay so first CL
CL minus okay so CL
okay so El it
so El it means
okay okay okay that's it discharge of ion okay na plus charge C CL minus an
ion okay na plus charge C CL minus an that's
okay so like the way so an C so electroly over that's
electroly over that's it next
so La
La okay okay
okay okay sorry
Orit okay so amount of gas or liberated or
okay so amount of gas or liberated or deposited is directly proportional
to okay so now here the Q Q is equal to I current into time okay
Q is equal to I current into time okay current
by uh where are you yeah equalent mass divided by farad equalent
divided by farad equalent mass
okay equalent mass divided farad into Q
equal what is equal mass equalent mass is
equal what is equ
Mass okay so mass divided by n Factor am I right so n
I right so n Factor so
formula Factor n Factor
M Mass okay in the mass the mass the M mass mass multip
mass divid by molar mass is equal to Q / n
/ n factor into F so what is given mass
factor into F so what is given mass divided by m Mass it's nothing but
divided by m Mass it's nothing but number of moles okay so that is nothing
number of moles okay so that is nothing none other than n so n is equal to Q
none other than n so n is equal to Q divid by n Factor
divid by n Factor UL byad so this is the
now so n q by n Factor multip by F that's
that's it
deposit Ser electrochemical
electroly ofation or evaporation is evaporation um Liberation or Liberation
evaporation um Liberation or Liberation or deposit directly proportional to
or deposit directly proportional to equal
equal Mass so W1 W2 is equal to E1 E2
one mo one Mo copper 2 plus one Mo AG plus one
F3 cond of electrolytic solution just
[Music] line so resistance and
electrolytic length so the length so length Okay so
l so resistance is directly propal to L and inversely proportional
and inversely proportional to resistance directly proportional to L
to resistance directly proportional to L and inversely proportional to a
and inversely proportional to a okay R is equal
okay R is equal to con L by
okay resistivity okay and
okay so unit r
okay so minus one okay next R CM
R CM s CM
cm that's it CM got it
CM got it so next cond
cond okay so g
g g
G okay so a by L
conductivity conductivity G so now now now no
no G Okay g a by L okay so G G cont it means G it's nothing but G is equal to 1
means G it's nothing but G is equal to 1 by R okay resistance
a think L okay
think L okay sorry L by a okay so inverse
ande CM inverse so these are the units of cap any more doubts my dear friends
of cap any more doubts my dear friends okay and again
okay and again l
l l l
constant that's it that's it
over nothing nothing else
okay okay so that's it any more doubts
nothing so conductance yeah so
conductance okay so cond conductance conductance conductivity so
conductance conductance conductivity so conductivity
conductivity conductivity what is
conductivity what is conductivity is known as
conductivity this is mol conductivity okay so M conductivity we know that
okay so M conductivity we know that conductivity per mole molar conductivity
conductivity per mole molar conductivity conductivity per mole what is
conductivity per mole what is conductivity K divid by per mole per
conductivity K divid by per mole per mole
right right so
okay okay this is M conductivity okay so M conductivity conductivity per Mo okay
M conductivity conductivity per Mo okay per Mo sorry
per Mo sorry small one solution okay solution into
the we know that s do CM inverse
that s do CM inverse right C
right C inverse k s CM
inverse k s CM inverse
inverse M number of moles right
Mo divid by L volume in lit it means
cmus 3 so two mole so this is a unit of molar
mole so this is a unit of molar conductance yes cm square
mole equalent conductance equalent conductance K divid by equalent mass
so k equal s so equalent
s so equalent equal yes CM
inverse okay equalent divided by CM Cub so unit
s CM inverse dot invers to dot equalent so this is a unit
invers to dot equalent so this is a unit of
of equalent uh conductance okay any more
equalent uh conductance okay any more doubts
doubts okay so relationship so
cond equalent conductance into n Factor Factor number of electrons involved okay
Factor number of electrons involved okay that's it
relationship equal is equal to n
to n Factor so that's it okay so that's it
Factor so that's it okay so that's it equalent conductance again limiting
equalent conductance again limiting conduct
liting conductivity increase okay sorry M
increase okay sorry M conductors on dilu
fix okay so electrical and I
conduct elro cond condu
vies okay so next variation of conductance
okay so next variation of conductance with
infinite or limiting conductivity limiting conductivity M conductivity at
limiting conductivity M conductivity at infinite
dilution okay so this is a
okay so this is a graph
graph okay
okay yal
yal MX
slope next uh c c c is nothing but mol
next uh c c c is nothing but mol conductance at infinite dilution am I
conductance at infinite dilution am I right that's
elro okay a power um a
okay a power um a y+ y b power X+
okay a infinite
a infinite D it's equal to the infinite dilution of
D it's equal to the infinite dilution of a weak electrolyte is equal to respected
a weak electrolyte is equal to respected okay respected
okay respected C infinite dilution of C
C infinite dilution of C in a y+
in a y+ okay okay
okay okay plus y molar infinite dilution of an
plus y molar infinite dilution of an Anon in a so be
Lambda a y+ and plus y lamb equal xus that's
dissociation degree ofo amount amount of dis dissociated div by
amount amount of dis dissociated div by total
same okay this term is known as solubility
okay yes x^ X Y power Y and x^ like x^ X Y power Y and solubility XY right sorry
Y power Y and solubility XY right sorry X+
X+ y

primary cell secondary cell primary recharge
echarge difference primary secondary the B electric energy
electrolytics MMI and goik sha okay so here dry cell dry cell Prim
reduction okay 2 plus electron fine next M2 okay manges dioxide and ammonia okay
mind like Magnus dioxide okay got it so cell potential 1.5 volt next lead
cell potential 1.5 volt next lead storage
battery storage battery the secondary this is secondary
this is secondary type lead storage battery okay the
type lead storage battery okay the secondary
second secondary speci this is reversible
reversible reversible Redux
charge okay discharge so charge and discharge okay so that's it this is our
discharge okay so that's it this is our storage
Okay so fical reaction it means
fical reaction it means compion yeah
compion yeah compion
F okay so first code oxidation like
okay so first code oxidation like cathodic process and anodic process
cathodic process and anodic process overall cell
overall cell reaction H2 okay H2 plus
reaction H2 okay H2 plus O2 H2 gas
O2 H2 gas okay2
okay2 gas
gas water okay so this hyrogen
water okay so this hyrogen fuel by the way so this
it ammonium Hydrox weak electrolyte okay so ammonium hydroxide is a weak
so ammonium hydroxide is a weak electrolyte
electrolyte infite
nh4 nh4 CL plus na CL minus na
o okay
minus nh4 don't
N4 so that's it option
okay infinite conductance of nh4 CL plus M infinite conductance of
nh4 CL plus M infinite conductance of strong
strong electrolytes
na minus strong like M INF conductance of Na that's it so option four is the
of Na that's it so option four is the right answer and
right answer and finally final homework when a l storage
finally final homework when a l storage battery is charged it act as
battery is charged it act as a when okay when let storage batteries
a when okay when let storage batteries charg keep it in your mind this is
charg keep it in your mind this is charging okay
charge yes that's it my dear friends that's it for today I hope
that's it for today I hope electrochemistry
okay I mean chapter both board exam as well
well as okay
see you later with one another session okay see you there by all by all by all
okay see you there by all by all by all bye bye bye bye bye bye bye bye back
