Question

In the electrolysis of water , Oxygen gets evolved *

1 point

At cathode

In the solution

At anode

All of the above​

Answer 1

Answer:

Overall reaction: 2 H2O(l) → 2 H2(g) + O2(g) The number of hydrogen molecules produced is thus twice the number of oxygen molecules. Assuming equal temperature and pressure for both gases, the produced hydrogen gas has, therefore, twice the volume of the produced oxygen gas.

Cathode (reduction): 2 H2O(l) + 2e−

answer- at cathode
