Faraday's First Law
Easychemistry
Faraday's first law states mass deposited is proportional to:
Select the correct option:
Solution
Incorrect! Answer:
Charge passed
- Statement: The mass (m) of any substance deposited or dissolved at an electrode during electrolysis is directly proportional to the quantity of electricity (charge) passed through the electrolyte.
- Formula: m∝Q.
- Charge Relation: Since Q=I⋅t (Current × Time), we can write m=Z⋅I⋅t.
- Constant: Z is the electrochemical equivalent of the substance.
- Dependence: It depends on both current and time, which together constitute the total charge passed.
