Hydrogen Peroxide Preparation Video Lecture - Chemistry Class 11 - NEET

hello friends this video on hydrogen
part when he is brought you by exam
clear calm no more fear from exam let's
now learn hydrogen parasites
what is hydrogen where side it is a very
wide chemical and it is using polishing
and control treatment it's very very
important chemical for industrial the
shame is which is given here
but before equal to the same this these
two it is discovered by 10 are in 1918
it's very very unstable it's very very
unstable and it doesn't occur freely in
nature it is used for rocket fuel tea
right and if you see this structure and
something like this there is a different
place actually you see this is in
different planes this is going inside
the planes coming outside the plane then
we will show more three-dimensional
structure of h2o to - to what - looks
like this this is H such you see this is
a different plane there are different
planes all together so you want to know
prepare hydrogen peroxides very unstable
you want to prepare it in the lab there
are two methods to actually do prepare
one is from sodium perhaps - from a
medium pair of sides so let's take a
sodium pair of side sodium parasite is
nothing but an A - what we do you add h2
so4
this and make it diluted and cold also
this will be lost
this guy will give any - soo in is -
because I told this guy is very very
reactive it is written hot also it will
react
thank you - to go to when you conserve
it so make the sulfuric acid very cold
and tell you same thing from barium
peroxide also again b b:e you want to
get from s 2 as a whole again same thing
you may be tightly with + cold so it
becomes yes before plus h2
the quality in this case is not very
good so what we can do is we can use
phosphorus so in this case in class
this quality is better these are all a
preparation in the lab you want to
prepare I didn't break said you can use
sodium peroxide or you can use very
imprecise Miriam presiding and reacted
somebody gets it always through your
whole order you suffer the industrial
preparation of hard duplexer is a tool
this is very widely used in industry so
there has to be a good way to prepare
hydrogen peroxide so two ways actually
the one is by the electrolysis of
50-person h2so4 the other is by two from
two entire time to eat i'll infraction
over there two ways so the first list of
my electrolytes of h2so4 in this case
what we do is we have this 50% i
situation for here right that your desk
you support and what we do will have a
reaction i'll show you what happens is
my h2 breaks into h plus plus h minus IC
in the edge of so 4 minus finds two hso4
minus ion react to form
peroxy die sulfuric acid and that we
have what we get is to this to this rate
is at cathode what happens cathode I get
qh+ gets two electron together again
spider gas
simple at a No since I don't have
electrons so what happened is this hso4
minus which we have got right so this
two reacts to form peroxy die sulfuric
acid there is a ch3 yes using these two
reacts to form this like the name of
this pure against two electrons I know
because two of them are getting must now
in this guy much we have caught a s 2 s
2 O in its whole thing right now seed i
sulfuric acid when you react this with
water because it is dying you would
normally person right which has water
here it gives you that's 2 to Esther
help so I have orders to it easy one
cathode you get hydrogen gas and here
you get
the next is from to eat I'll
anthraquinone so bitch in the color so I
have to so the next was from to eat high
and throw quenelle so in this it is
pretty easy you have to tile and throw
you know when you pass oxygen to it it
gives history so if we just oxidation of
two entire anthraquinone
we give you estimate I can show you the
reaction for this let's draw in Thailand
shokunin
so this is my to meet hi
there's two Italian opinion when you
oxidize in a year this will give you and
sorry this has a wedge wedge to watch
time and so to Nadia this guy will give
you because he comes double bond oh
right and plus estelí very cool and if
you want to get it back because we just
can't use this costly compounds to
create what h2o to will again into
hydrogenation in presence of my perineum
Monica catalyst so what will happen is
if you add hydrogen to this this becomes
mine so how can we increase the
concentration of s2 because the urge to
move you retreat this has very low
concentration but we can't increase just
by boiling it because it's very reactive
it's okay so what will happen the moody
boil it will decompose into oxygen water
and I were to increase the concentration
on this h2o so there is a step involved
the first is you have to move do if I
put it just very slowly on water bath
very schooling and then we have to
evaporate a natural chamber and then you
distilled you distillation and a reduce
pressure and low pressure and then you
have to remove the last trace of water
and that's how you increase the
concentration of s2 is already tedious
process because it's very very reactive
you do very slow evaporation in the
water path and the vacuum chamber do the
evaporation and then you
this legislation in the reduced pressure
and then you remove the last result
