Question

During electrolysis electrons are:
А.Lost
B. Gained
C. Lost by cations and gained by anions
D.Gained by cations and lost by anions​

Answer 1

Answer:

lost (a) is the right answer

Answer 2

Answer:

The correct option is (D) Gained by cations and lost by anions.

Explanation:

• During electrolysis, there is an exchange of electrons taking place at the electrodes.
• At cathode, the cations gain electrons from the solution and get deposited there.
• At anode, the anion lose electrons from the solution and get deposited there.

For example:

1. Gaining of electrons by sodium cations:

$Na^{+} + 2e^{-}$ → $Na$

2. Losing of electron by chlorine anions:

$2Cl^{-}$→ $Cl_{2} + 2Cl^{-}$

Conclusion:

During electrolysis, electrons are gained by cations and lost by anions.
