Question

Give the chlor-alkali reaction. Name the gases evolved at the cathode and anode. State one use of each of the gases.

Answer 1

NaCl+H2O=NaOH+H2+Cl2
cathode-hydrogen
anode-chlorine
uses
H2 is used for hydrogenation of oils to form fats
Cl2 is used to form bleaching powder...

Answer 2

When electricity is pass through the aq. solution of sodium chloride it decompose to form sodium hydroxide .this process is called chlor alkali process.
reaction:
2NaCl(aq)+ 2H2O(l)
= 2NaOH (aq) +Cl2(g) +H2 (g)
in cathod= hydrogen gas
in anod= chlorine.
uses:hydrogen =fules ,
ammoniun for fertiliserz
chlorine = water treatment, pesticides.
I hope it's helps u alot plZ marks as brilliant answer
