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

Answer»

9.65A
19.3A
0.965A
1.93A

Solution :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
