During the charging and discharging of a nickel-iron cell____________?
Correct answer: B. water is neither formed nor absorbed
- A. corrosive fumes are produced
- B. water is neither formed nor absorbed
- C. nickel hydroxide remains unsplit
- D. its e.m.f. remains constant
Explanation
In a nickel-iron cell, the charging and discharging reactions transfer oxygen between the electrode compounds without a net formation or absorption of water. This distinguishes it from the water-consuming and water-producing reactions of a lead-acid cell.
