Solution

The key process of electrolysis is the interchange of atoms and ions by the removal or addition of electrons to the external circuit. Nickel is deposited at the anode and sulfate ions remain in solution forming sulfuric acid while $O H$ ions are released as oxygen gas. The bulb glows when the flow of electrons takes place.
