Find the time requried to liberate 1.0 litre of hydrogen at STP in an electrolytic cell by a current of `5.0 A`.

Text Solution

Verified by Experts

The correct Answer is:
B
Mass of 1 litre hydrogen `
`=(2)/(22.4)gm`
` m = Zit (2)/(22.4) = (1xx5xxt)/(96500)`
`rArr t = 1723.21 sec = 28.7 min = 29 min
