(a) Oxygen ions are produced at positive carbon electrode.
(b) Hydrogen ions are produced at negative carbon electrode.
Explanation:
- When small amount of acid is added to water, it increases the conductivity of water and it is called as acidified water.
- When electric current is passed through acidified water, it ionizes into hydrogen ions and another ions depends on the acid that is added to water.
- The hydrogen ions move towards cathode and liberates hydrogen, the ions deposited at the anode also releases hydrogen. In this way, the hydrogen in the water is never reduced and acid is never consumed.
- So, acidified water is widely used in electrolysis process in battery.
