Q. The amount of substance deposited by the passage of 1 A of current for 1 s is equal to

A) Equivalent mass
B) Molecular mass
C) Electrochemical equivalent
D) Specific equivalent
Explanation

(c)
According to Faraday Ist law
$w\ = \ Zit$
Where, $w$ = amount of substance
$Z$ = Faraday constant or electrochemical equivalent
$i$ = current in ampere
$t$ = time in second
If $i\ = \ 1,\ t\ = \ 1,\ w\ = \ Z$
