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:

Options

A. 9.65A
B. 19.3A
C. 0.965A
D. 1.93A

Answer

A

Explanation

No of moles of `H_(2)=(1.12)/(22400)`
`therefore` No. of equivalents of hydrogen`=(1.12xx2)/(22400)=10^(-4)`
No. of faradays required`=10^(-4)`
`therefore`Current to be passed in 1 sec. `=96500xx10^-4`
`=9.65`A
