A steady current of 1.5 amp flows through a copper voltmeter for 10 minutes. If the electrochemical equivalent of copper is 30 x 10⁻⁵ g coulomb⁻¹, the mass of copper deposited on the electrode will be
Options
(a) 0.50 g
(b) 0.67 g
(c) 0.27 g
(d) 0.40 g
Correct Answer:
0.27 g
Explanation:
We have, m = ZIt where, Z is thr electrochemical equivalent of copper.
m = 30 x 10⁻⁵ x 1.5 x 10 x 60
= 0.27 gm.
