Q. In the electrolysis of acidulated water, it is desired to obtain 1.12 cc of hydrogen per second under STP condition. The current to be passed is

A) 1.93 A
B) 9.65 A
C) 19.3 A
D) 0.965 A
Explanation

(b)
No. of moles of $H_{2} = \ \frac{11.2}{22400}$
No .of equivalence of hydrogen
$= \ \frac{1.12\ \times 2}{22400} = \ 10^{- 4}$
No. of Faradays required $= \ 10^{- 4}\$
∴ Current to be passed in one second
$= \ 96500\ \times \ 10^{- 4}$
= 9.65 A
