Question

The electrochemical equivalent of a metal is 0.126 × 10-6 kg/C. The mass of the metal that a current of 5A will deposit from a suitable bath in 1 hour is

Options

A)
0.378 × 10-3kg
B)
0.227 × 10-3kg
C)
2.268 × 10-3kg
D)
0.0378 × 10-3kg

The correct answer is A.

Explanation:

Note: The electrochemical equivalent, sometimes abbreviated Eq, of a chemical element is the mass of that element transported by 1 coulomb of electric charge. The electrochemical equivalent of an element is measured with a voltameter.
