Question

In chlor - alkali process why Clorine obtained at Anode and Hydrogen gas at Cathode
and sodium Hydroxide near cathode ??

Answer 1

In the Chlor Alkali Process Chlorine is obtained at Anode because it is a negative ion and negative ions are attracted towards opposite charge that is positive .

Similarly Hydrogen is obtained at Cathode because it's a positive ion and cathode is negative electrode.

NaOH is obtained near the Cathode because NaOH is a positive ion and thus it gets attracted towards Cathode
Hope this helps

Answer 2

Hey dude here is your answer -

In chlor-alkali precess chlorine obtained at anode and hydrogen gas at cathode because -
chlorine has minus charge so, it attract towards positive anode and hydrogen has positive charge so, it attract toward negative cathode .

sodium hydroxide obtained near cathode because Na has positive charge

Now , reaction is --
The reaction at the cathode is:

H2O(l)+2e−→H2(g)+2OH−H2O(l)+2e−→H2(g)+2OH−

The reaction at the anode is:

Cl−→12Cl2(g)+1e−Cl−→12Cl2(g)+1e−

The overall reaction is as follows:

NaCl(aq)+H2O(l)→Na+(aq)+OH−(aq)+H2(g)+12Cl2(g)NaCl(aq)+H2O(l)→Na+(aq)+OH−(aq)+H2(g)+12Cl2(g)
