Answer 1

On passing electric current through a conducting solution, a few chemical reactions take place

Examples -
(A) When electric current passes through water, water dissociates into hydrogen and oxygen. Hydrogen is deposited over the negative pole and oxygen is deposited over positive pole. Deposition of hydrogen and oxygen at different poles is visible in the form of bubbles.

(B) Sometimes, the colour of solution also changes when electric current passes through it.
