Heavy Water-Properties and Uses Video Lecture | Chemistry for JEE Main & Advanced

hello friends this video in hydrogen
part 24 is brought to you by example
your calm
no more sphere from exam let's learn
heavy water d2 what is d2 I mean what it
is nothing but it's oxide of heavy
hydrogen we have seen there three
isotopes of hydrogen right so one is H
one is d minus T H DN T this is
deuterium
so this oxides of deuterium is heavy
water that is d2 oh right and also
called deuterium oxide and this
discovered by you Ray it is very
extensively used as moderator in nuclear
reactors you must have sorry this
nuclear fission and fusion reaction in
physics there you have seen this d2 is
uses moderator to control the speed of
the particles right which are gone the
nuclear reactions and it is prepared by
too long hydrolysis or electrolysis of
water it is also produced by some Bible
words in some fertilizer industries so
generally it is prepared by too long
Electra lysis of water now I will see
how this video is prepared it is
prepared by the prolong electrolysis of
ordinary water it is also prepared by a
fractional distillation of 40 water in
case of fractional distillation the
boiling point of s 2 and D 2 are
different that is used so for H to the
boiling point is 373 point 2 Kelvin and
for D 2 or the boiling point is 370 4.3
Cal there is a small difference but
there is a difference and we take
advantage of this difference in warning
point and we fractional distillation of
the ordinary water to get D 2 and it is
literally in a very small quantity
because the percentage of D 2 in normal
ordinary water is very less so during
complex rational detonation vegans
generate D 2 so we will talk about the
physical property of this
Lito it is colorless tasteless odorless
liquid just like water its physical
properties similar is almost similar to
water it's almost similar to water
we talk about chemical property that is
also similar to whatever the reaction is
stored silver so if you see the chemical
reactions
you should have h2o obviously we need to
see a C 2 plus D 2 is called C 2 D 2
plus C or D similarly a su 3 plus T 2 is
d 2 I so for al 4 C 3 plus D 2 is C D 4
so almost similar to our water but the
rate of reaction is little too slow
we'll talk about the uses of V 2 so it
is used for a Newton water I told in the
case of nuclear reaction it is used to
model the speed of the particles
involved in the nuclear reaction it is
used to prepare deuterium the D as I
told the deuterium D it is used to
prepare that and it is also used as a
tracer compound you must have if you
have washed the Librium chapter they
have been apps told that we even to find
whether the urine is dynamic or not
right so to confirm the eclairisse
dynamic we use the detuvo Ashly
and there we told that we have this d2 o
h2 or this compound mix and after some
time we found that we have different
varieties of compound right so we used H
and D combine together to find the
equilibrium to prove that the ignoramus
dynamic in nature so it is used for
tracing the Tracy compound we take some
examples knowing the properties of s 2
and duty or do you think D 2 can be
useful to think you know t2o can't be
used for drinking purpose because it
slows the reaction and it is harmful
actually which consumed a lot it is not
