L4 : Competitive electron transfer reaction - Redox Reaction, Class 11 Video Lecture

hello friends this video on docs
reaction part 4 is brought you by exam
fear calm no more fear from exam before
watching this video please make sure
that you have watched part 1 - Part 3
it's understand the competitive transfer
electron transfer reaction there's
always competition in life and the
competition is for us for everyone
actually I believe four elements human
the combination is your chain typically
see if a person is running you know
Olympics is running to get name Fame
study can be stable in life we are
studying on student study you know
people who job that is business this
because they want still many lives it is
the elements also want stability in
their life and they can achieve this by
gaining or losing electrons these on
which circular periodic table they lie
and I'll explain this things
particularly in class 11th and chapter
if it don't if you can still not clear
please wall chapter once again so if you
see of students what they are raising
their racing just to when they want to
be winner they want to be stable and
lives in road if you see if you have
zinc in a copper of sulfate or copper
nitrate solution
you put the zinc in a copper sulfate a
copywriter solution after some time you
see the color of the copper nitrate
solution which is dark blue will turn
very light blue and zinc is a little
brain color the copper from the copper
nitrate solution will get deposited here
you will see good deposit of copper here
you can do this in the lab you can have
take a drink in take copper nitrate
solution of copper sulphate solution
this depend
you see the dark color the cotton item
solution is the minimizer it almost
becomes colorless and you see a copper
deposits and then check the question is
why it happened so if you see the
reaction would happen is here jQuery
actually with copper sulphate solution
Jane got oxidized
Jing became jealous to write it last
lecture and copper god produced copper
nitrate produced in copper and that
copper is default layer' but if you flip
this side if you take a Jing nitrate
solution and put a copper strip you keep
it for ours months years they'll not be
any reaction why because if you see zinc
can oxidize more easily than copper zinc
can oxidize more is even copper if you
talking what the oxy oxidation property
is zinc is a stronger oxy then then
copper and there is a property that
depends on the atomic structure because
zinc want to lose electron more than
copper to become shape and then the
competition area jinkin copper similarly
for other metals also we can create a
comparative chart which can help us in
predicting with a reaction - ah because
i'm in this case zinc plus copper
sulphate the reaction happen but copper
plus zinc sulfate reaction didn't happen
why because we know that the reactivity
chart with the develop reactivity chart
we know that zinc is more reactive in
copper zinc want to lose more electron
more than copper so we can develop a
chart chaotic example if you see if you
react jing with copper you get this
reaction you react copper with silver
nitrate kind of stuff then you will see
again you get copper plus the bins
copper is more stronger than silver
nitrate or copper want to lose electron
more badly than silver right similarly
again there are metal activity
like this that means lithium wants to
dela want to release or give electron
mode easily I want to get oxidized more
easily right so because it becomes a
like trust me a more stable similarly
potassium calcium sodium and this is the
order gold if you see in the last that
is very unreactive also and that's why
we may call on them as gold so this is a
reactivity charred if we say with this
chart we can find if you say that I have
a reaction between zinc and let's
suppose this guy copper sulphate I can
see that we actually happen because ink
will try to become zinc sulphate right
or aluminum and zinc sulphide L say yes
L urea will become every in last rate
but if I have iron and zinc sulphate no
the reaction won't happen because zinc
will zinc sulfate that means it is zinc
is already in class - and I'll it is in
free iron so Jing had more tendency to
become zinc plus 2 then iron so it will
be in this stage but if it is zinc and
iron plus 2 let's suppose so then zinc
will become zinc plus 2 and I 1 will
become correct do the middle activity
series and this is developed using tons
and tons of experiments
so it's good to remember this activity
series actually thank you visit exam
