STANDARD Chemistry Faraday's Laws of Electrolysis MCQ Question
If 54 g of silver is deposited during an electrolysis reaction, how much aluminium will be deposited by the same amount of electric current?
2.7 g
4.5 g
27 g
5.4 g
Correct Answer
Detailed Explanation
1 Faraday (F) deposits 108 g of Ag (Ag⁺ + e⁻ → Ag). 54 g of Ag will be deposited by 1/2 F. 3 F deposit 27 g of Al (Al³⁺ + 3e⁻ → Al). 1/2 F will deposit 4.5 g of Al.
