Answer 2

Answer:

When electrodes are immersed in water and current was passed through water; bubbles of oxygen and hydrogen are produced. Oxygen bubbles are formed at the electrode connected to the positive terminal.

Explanation:

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