Hello assalamualaikum warahmatullah
wabarakatuh good to learn the
third segment for the lesson of the skin
we will start to prepare when about
this time we will learn about
making Colloids which yesterday were the
properties of colloids Now we will
learn about making Colloids
How to make colloids
Hi physically physically to make
colloids is this this is the
middle size between the solution and
suspension between the solution and suspension there
is a cord in the middle here Mecca
to form change the size to the
size of the colloid then inevitably the
suspension whose
size is larger than the colloid
will be reduced to the size of the Cholid whose
solution is smaller in size on the
skin will be combined to the end
so that it has the size of the colloid
now the ways or names of ways to
change how to make skin by changing the
size which was originally the big one to
be smaller that's the name is the
dispersion method originally larger to the
size of the Cholid that's because dispersion then the
gratitude is smaller than the
golek then combined combine to be
big that's the name of the method there is the
condensation method I condensation here there are
four then dispersion here there are three
we learn first jatis version
dispersion dispersion breakdown
mechanically coarse grains are
ground until fine then stirred
with a dispersing medium to become fine coarse
Sis the coarse ones are ground and
mixed with a dispersing medium
mechanically for example across is ground
until the size of a colloid please mix it
with water it will be more mechanical sulfur sol
Hi then the peptization method
peptization method This is a way of making
Colloids from coarse grains with
Not ground but with the help of a
peptization agent a substance that breaks up the agar-agar agar
-agar that is when it has not been mixed
with water it is larger in size
which is the size of a colloid but when
given hot water the hot water will
break the agar into
smaller sizes so that the size has a
colloid size then giving hot water
to the agar is called feat
peptization method
Hi hydrocellulose by acetone it will
change the size of nitrocellulose into
small people rubber by gasoline
The problem is if you have rubber don't
squeeze it so it doesn't swell why does
gasoline dissolve HK red is zarut
in gasoline it will break down in
gasoline If there is a lot of gasoline and
so on Yes, this can also be
peptized by h2s, this h2s and in front of
aloh3 times by KL, it will change
its size to be smaller,
peptization method, peptized
Hi, Bredig arc method,
Hi, Bredig arc, big batik, from the
key words, it is electric fire jump, jump,
jump,
electric jump, electric jump,
electric jump, with the electrode given,
then an electric jump occurs, the
materials will dissolve, the materials
will be Harun, this is usually a bit if
later on the experiment of making
metal coatings with metals, when
coating with metals with metals,
electro-electro and later the lesson,
Pastika, is produced, then when the
metal coating event
occurs, it will cause the solution, the
boy, to change to brown,
change to black, change that, the process of
dissolving metal.doc, which in a
way that involves
electricity is called a Bredig arc, a
way like that can be done with electricity, it
involves electricity so that a
solution occurs, the list is like this, the dispersion method, the
large ones are changed to the size of a
colloid by dispersion from the results of
breaking down a compound that is
large from the skin to the size of a match, the
dispersion method, the method the second is the
condensation method the condensation method is the
particles in two
true solutions with smaller sizes
fold the tails combine into
larger particles the
size of this colloid is the
true solution Rutan yes does not cause
symptoms of the tyndall effect two natural tonic oceans
mixed it turns out can become
solutions by forming results
producing compounds that
have a size the size of a colloid Well
if this is mixed it produces
this this method is called the condensation method
Hi there are 4 condensation methods 1234
redox methods not all redox
produces condensation there is one there
are some masks that are still and the
skin I am a teacher to make it
easier to discuss which redox
produces the skin khazzani phase Aqua
Aqua Aqua the result is this is the size of a
colloid position does not settle but
flies the size of a gas chemical colloid Aqua
Aqua Aqua this is a true solution so the beginning of a
true solution true solution
filming location me or liquid I Or I am
here gas or I agasto I this
forms sulfur the size of a keloid the work of
making gold sol from the center of the
haucl4 solution with routine k2co press the results
Hi here Later it was
used by Nazi Germany to
hide to cure gold
by changing the gold into
haucl4 then adding this
added with Ha then the gold
dissolved in the liquid so that it
was thought it was not gold but in it was
still used by people so that it was not
taken by Nazi Germany during the
second world war h2s and sotk spkd
then redox reaction Then the
second hydrolysis hydrolysis from the
basic word hydrolysis hydro is water H2O
ISIS broke What does lysis mean
is the process of breaking down a compound
that involves water the process of breaking down a
compound that involves water
for example FeCl3 given water yes the
true solution breaks it turns out that
given water the true solution
Hai changes it breaks it FTV breaks with
CL vcl expelled by H2O yes with the
other fb only with oha from
breaking it experiences lysis because of the presence of
water Well it turns out this has a
larger size in its true size its
size is the size of a colloid
then the event of the formation of FeOH3 which
has a larger size
than the size of this true solution is a
hydrolysis event because it
involves the addition of water solvent it
turns out that it becomes a colloid yes
if in water it becomes a wall of
FeCl3 solution then it is formed Soul Calibur This
is eating eels sound changes again
because this reaction process with this
has entered the reaction added FeCl3
increased This is eating So my mistake is
giving it again so
Hi double decomposition
double decomposition decomposition and double
decomposition is if a
compound changes composition with the right
there are two pairs there are two pairs
that exchange pairs there are two
pairs that exchange pairs
if he is two pairs then it is said to be
double Because he is one pair off
exchanging pairs his food decomposition
example this h3a Spot 3 with h2s h2se
there is a liver quart 312 double decomposition
he changes his composition this one with the
original sulfur with the 19th which
with ha now sulfur with as
decomposition changes his composition this
changes his composition not with the
weekend how much is the price Boss
enough is not there is a pair there is a
double compound double decomposition does always
double decomposition produce skin there is
no skin production there is
double decomposition that
produces colloids yes This is also
double decomposition produces
this compound there is arthasejati true solution quickly
chat-id arthasejati Aa If the ocean is true Like
this is still skin then the
event is a condensation event the
condensation event the size of the skin
becomes more upright Quran the true solution
becomes the size of a match the
last double decomposition the
making of the last Colloid falls solvent replacement
solvent replacement
Florida is replaced the reason is not Brother
approach and this event is
shown another scar so that there
will be two oceans actually because
there is a lie solvent
replacement equipment replacement the event of the
formation of colloid particles because of the
replacement of the solvent used
for example if rattan is saturated with calcium and
mixed with alcohol then
a skin is formed in the form of this gel this love is
still with alcohol he is
given it so the size is
bigger but if alcohol with
water he is liquid he dissolves instead of the nature of the
solution but Trenggalek please
he actually becomes the size of the code so it is
bigger the event of buying alcohol as a
substitute for this water solution is called
solvent replacement yes for
making Colloid then I repeat
from the front of the cholesterol fence two namely
method is condensation method is
condensation method is he will
change the true solution to
the size of a colloid
if the dispersion method is he changes
the size larger than the volume of
bankole to the size of a
smaller size so the thanksgiving of colloid
by dispersion tragic That version has 31
mechanically ground Wow, the
peptization method is given some solvents
so that the dissolved size
becomes the size of the skin so the size is
smaller, the session box method then the
bredig arc because there is the influence of Line that
electric sparks so that the
metals will dissolve into the
solution, the metals to will dissolve in the
solution, maybe this can be known
Why is there why is there local there is metal
if there is listen eyebrow or metal
exposed to electricity to become black characteristic That
is the influence of the bredig arc How
can it be black, actually there are
loose metal particles that are
loose that are scratched so loose that
because of the influence of electric jumps
Hi, have you reached where it is
Hi, pt.tsa is currently on the subject, already in the
way of making Colloids Well now there
are practice questions 123
Hi, this looks main, is this still
with colloids, the meaning of korid
is explain the components of the
skin, call, there are several
components of its composition, mention two examples of
priyang there are funds encountered in life
in the field of food cosmetics industry,
pull out lentisco, there are still two since 123, the
second, complete the following table, what is the
name of the gas in liquid in gas what is the
name Jordan I got his name Jaya
in Peterpan his name is in
politeness and third complete the
following table smoke remember smoke its
constituent components what and what so that the
type can be known
Hi fog what are the components and what is its
function the type of skin can be known
Is it chalk ransom or aerosol or
should forget or emulsion or what is the
component This is filled
hi hi
paint then the fourth is by
dispersion and condensation method what is the
description what is condensation
Hi later if there is say dispersion
kapaha modis that version once the condensation is
finished by specializing
in colloidal charge his efforts in
making Colloid what is meant by
saredo cotton by default the event is still
said how laptop decomposition
controls skin temperature What is
meant by separate mechanical method
who mechanically is the beach
understanding only because it is filled only TTL
1234 this is for your own practice
since you collected what is collected
is what is in the link below in
this video section later I will attach the link The
question is multiple choice there are 20
please click the link to answer there
multiple choice 1 to 20 each
question the score is 5 each, thankfully 5
lions, the value of this status is to
see Septian Mandiri, you just
press it, you collect it
yourself, then what is collected, what is
done is what is in the
description link in the attachment below for
making Syahrini's skin, hopefully it
can be understood, I am a leftist,
