Answer 2

The product obtained on cathode and anode by the electrolytic decomposition of acidulated water​.

Explanation:

• When we carry electrolytic decomposition of acidulated water, we get hydrogen gas at negative electrode(Cathode) and oxygen gas at positive electrode(Anode).
• In acidulated water, a small amount of acid is added to generate free ions because pure water is non electrolyte.
• The electrolytic cell (Hoffman's Apparatus) has a negative charged Cathode and a positive anode.
• When electricity is passed in the cell, the positive hydrogen ions migrate towards cathode, accept electron and become hydrogen gas: Reduction takes place.
• The negative hydroxide ions migrate towards anode, loose electron and become oxygen gas: Oxidation takes place.
