Methods to Remove Temporary and Permanent Hardness (part - 3) Video Lecture - JEE

hello friends this medium hydrogen part
eating is a brought to you by exam fear
calm no more fear from exam this and
understand the organic exchanger method
here so here we use organic ion
exchangers we have two different kind of
ion exchanger power than you here this
is made first here one we have the
cationic anionic she will tell you what
is this
so here we use cation anion exchanger so
this is my cationic here let me write
first no time exchange it is it there's
my exchange I will talk about is a
tomato just so we have cation exchange
in an ion exchange so what is this piece
of cationic combination these are
nothing but my complex organic molecules
there are complex organic molecules
complex and they are attached to either
a Citigroup what BC you talk about a CT
group it can be
s3x to what BC group it can be Oh H - H
- correct so my easy be easy be group
are the one which are capable of
exchanging H+ ions and they call cation
exchange so let me try it first so I
haven't done the cat ion exchangers and
ion exchange isn't so let me write these
bases first so if you see the cut time
things change reason it is something
like big molecule with a sutra which and
then or a big molecule with co h know we
talked about an ion exchange is in which
in the color like talk about online
exchange reason it is nothing but my
these groups a big group with H - o with
histories
these are my reasons used right so hope
you understand this my reasons my cat on
exchanges in the nomination reasons so
this guy is key people of exchanging h
minus sign or English - ions and this
guys see people love exchanging s
disguise right so these are my cations
and anions exchange reasons correct
so now I start with the process just you
understand what does the reasons they
are nothing but a complex organic
molecule which has easily curve is equal
to attached the SD group can be a so 3h
or CU h the basic group can be H - 2 -
the a student group the one which - was
hasty group they are called cation
exchange resins for example this so3h or
CU h minus C which they are capable of
exchanging H+ ions the on ion exchange
resins have h minus of LS - - the end
and they are capable of exchanging Oh H
- of in the students
correct these are made again basic
reasons so let me start with the trusses
what happens from here the hard water
runs hard water comes and here this is
cation exchange AC that is my it has
nothing but my it will give H+ ions and
this is my an ion exchange resins ready
give so it comes here hard water comes
here you ignore this part noise of non
hard water comes here it is attached to
h plus ion to you so hot water is
nothing but my calcium CA plus 2 ions
let me right direction so i have seen
two glass hard water that reacts with
this reason this guy so both has H so I
can write as h plus and this structure
like this structure right h plus in this
dot right this is quickly regulators big
this is h cousin big dot so when you
react it becomes CA and this big dot was
whatever it was begin part 2 then this
becomes th may see I can give it a name
oz if you want if you have continue with
this let me give it a name X plus raisin
becomes CA raising 2 into H correct
so I got in this you see what I had what
I got H+ correct so if it is a chlorine
so it will be CL minus and a Superman
boosting also will be here and now this
goes up here now this guy's our anion
exchange isn't like you know this guy
will have h to us you see no - then I'm
assuming that my hardness is due to see
is near to this as you mean in this case
so I took CA plus to write this nothing
but cacl2 so I got H+ and Cl minus here
now this H+ and Cl minus will react with
an ion exchanger so here let's suppose I
have the CL - it will react with this
thing
Oh H - and some reason right ways - long
chain so it will give you CL - then some
reason and it will give you H - because
this guy is capable of exchanging oh Sh
- so it will exchange this this guy is a
capable of exchanging H+ ions so this
guy will exchange with cancer so I'll
get this now you see I have got h+ here
i got H minus here so I Ament add h plus
a know which - what you get is yesterday
in that I get Q this is demineralize
watering this you admin those two
another taste
correct this is how the world processes
now same thing here of the regeneration
because after some time my H+ race it is
gone it becames seeing it isn't right
because after some time my H+ raisins
the H+ raising this becomes Sierra's
input and this becomes CL raising so
these are are my they think we should
not be used
I have to regenerated so what I do here
is in this case I pump in as seen in
this case I slowly - oh right sprinkler
so the moment we pump it s CL here what
happens is my C arrays in C here is into
reacts with HCl and it gives back the
oldest matter
the reaction to change the reaction this
should be it is I had my reason is he
risen to the moment I react with SC n
one here you see CL - right
plus if you see it Plus this this is
what I get
similarly in this case anyway I have my
CN minus ways in this case I will react
with any watch it will give me a wish -
fine ah listen is the reason why he was
having own cut it back and either get
anything so in this case if you see the
regeneration it works like this you once
you feel that the results are exhausted
stop the core sense regenerated remove
the waste from here because you have all
this NaCl not just remove the waste from
him there has to be a pipe you remove
the waste you remove the waste close the
tap again start the process that is how
it works
hope you understand so this is nothing
but all the ring exchanger method where
we have Pathan exchange reasons and you
have an ion exchange reasons okay
can I die on Action News has capability
of changing H+ ions an ionic series has
capability of exchanging h- minds so we
react calcium chloride which is the
hardness with first with the cation
exchange resins so it becomes calcium is
trapped okay and then you have the
chlorine we have to react with again
this an addiction is the chlorine is
time both calcium and choline is trap
and we get pure water and you have to
regenerate this reason so we sprinkle
hydrochloric acid in the cation exchange
resin chamber and we will sprinkle
sodium hydroxide in the anion exchange
resin channel thank you visit exam
