Q1. (1) Formation of gas bubbles on the electrodes.

Q2. Change of colour in solution

How does an electric current causes chemical change?

The passage of an electric current through a conducting solution causes chemical reactions. As a result, bubbles of a gas may be formed on the electrodes. Deposits of metal may be seen on electrodes. Changes of colour of solutions may occur.

Q1. (2)

Q.2 (4)

What are the observable changes which happen to a solution when electric current passes through it?

When an electric current flows through the conducting solution, it causes a chemical reaction (or chemical change). These chemical reactions may produce following effects: i) Bubbles of gas/es may be formed on the electrodes.
