Two Faraday of electricity is passed through a solution of $C u S O_{4}$ . The mass of copper deposited at the cathode is: (Atomic mass of Cu = 63.5 amu)

Options:

Answer:

Solution:

${Cu}^{+ 2} + 2 e^{-} \to Cu$

2 Faraday charge deposits 1 mol of Cu, or

$2 F \equiv 2 Equivalents of Cu$

Mass of Cu deposited $= 2 \times \frac{63 .5}{2} = 63 .5 g$
