Faraday’s First Law of Electrolysis explains how the amount of substance produced at an electrode depends on the electric charge passed through the electrolyte.
Explanation:
- The mass of a substance deposited or liberated during electrolysis is directly proportional to the total electric charge passed through the electrolyte.
- More current or longer time → more substance formed.
Key Points:
- Mass deposited ∝ Electric charge
- Charge depends on current × time.
- Helps calculate how much metal is plated or gas is produced.
In short: Faraday’s first law says more electricity = more substance formed during electrolysis.
