Question

why should we add a few drops of H2so4 in electrolysis of water​

Answer 1

Answer:

To increase the conductivity of water a few drops of sulphuric acid is added . Being a strong acid it can ionize completely to release H+ ions. These H+ ions are responsible for the conduction of electricity. To carry out electrolysis in water,a few drops of sulphuric acid is added to the water.

Explanation:

Answer 2

To increase the conductivity we add few drops of sulphuric acid in electrolysis of water.

Step by step explanation:

Electrolysis;

The process by which an electric current is passed through a substance to cause chemical change. During the chemical change the atom may gained or loss of electrons.

Electrolysis of water;

Decomposition of water give hydrogen and oxygen gases by the passing through the electricity.

The chemical reaction of electrolysis of water is as follows.

$\bold{2H_{2}O+electric\,energy\rightarrow O_{2}+2H_{2}}$

Pure water does not conduct electricity. To increase the conductivity of water we can add few drops of sulphuric acid.

And the water completely dissociated into positive and negative ions.
