The electrochemical equivalent of a substance is numerically equal to the mass of the substance deposited if a current 1 flows through the electrolyte for 0.25 seconds. The value of 1 is

Options

A. 1A
B. 2A
C. 3A
D. 4A

Explanation

According to Faraday's first law of electrolysis
m=Zlt
Given m=Z(numerically equal)
t=0.25 sec.
`therefore 1=(1)/(t)=(1)/(0.25)=4A`
