Question

A current I is passed for a time t through a number of voltameters. If m is the mass of a substance deposited on an electrode and z is its electrochemical equivalent, then

• A. $\frac{zIt}{m} = \text{constant}$
• B. $\frac{z}{mIt} = \text{constant}$
• C. $\frac{I}{zmt} = \text{constant}$
• D. $\frac{It}{zm} = \text{constant}$

Answer 1

Answer: (A)

$\frac{zIt}{m} = \text{constant}$

Answer 2

$m = Zit \Rightarrow \frac{m}{Zit} = 1(\text{constant})$
