Question:
0.592 g of copper is deposited in 60 minutes by passing 0.5 amperes current through a solution of copper (II) sulphate. The electro chemical equivalent of copper (II) in g/C is:
0.592 g of copper is deposited in 60 minutes by passing 0.5 amperes current through a solution of copper (II) sulphate. The electro chemical equivalent of copper (II) in g/C is:
Show Hint
The electrochemical equivalent is calculated by dividing the mass of the substance deposited by the total charge passed through the solution.

- \(3.3 \times 10^{-3}\)
- \(3.3 \times 10^{-4}\)
- \(6.6 \times 10^{-3}\)
\(6.6 \times 10^{-4}\)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The total charge passed is \( Q = I \times t = 0.5 \, \text{A} \times 3600 \, \text{s} = 1800 \, \text{C} \). The electrochemical equivalent \( k \) is given by \( k = \frac{\text{mass deposited}}{\text{charge passed}} = \frac{0.592}{1800} \approx 3.3 \times 10^{-4} \, \text{g/C} \).
