Question

Name the product formed at the anode during the electrolysis of acidified water using platinum electrodes.

Answer 1

Electrolysis of acidified water:-

1. During the electrolysis of acidified water, it is split into two products which are hydrogen and oxygen gases. $\underset{\mathrm{Acidified}\mathrm{water}}{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}\rightleftharpoons \underset{\mathrm{Hydrogen}\mathrm{gas}}{2{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Oxygen}\mathrm{gas}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}$
2. At the cathode, hydrogen is formed, and oxygen is formed at the anode.
3. This electrolysis is done using platinum electrodes.

Therefore, the product formed at the anode during the electrolysis of acidified water using platinum electrodes is oxygen.
