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

Answer»

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

Solution :No of MOLES of `H_(2)=1.12/22400`
`:.` No. of EQUIVALENTS of hydrogen
`=(1.12xx2)/(22400)=10^(-4)`
No. of Faradays required `=10^(-4)`
`:.` Current to be passed in 1 sec. `=96500xx10^(-4)`
`=9.65A`
