NEET 2024 Chemistry Faraday's Laws of Electrolysis MCQ Question
Mass in grams of copper deposited by passing 9.6487 Å current through a voltmeter containing copper sulphate solution for 100 seconds is: (Given : Molar mass of Cu : 63 g mol⁻¹, 1F = 96487 C)
31.5 g
0.0315 g
3.15 g
0.315 g
Correct Answer
Detailed Explanation
Using the formula m = (ItM)/(nF), where I = 9.6487 Å, t = 100 s, M = 63 g/mol, n = 2, and F = 96487 C/mol, the mass m = 0.0315 g.
