The volume of hydrogen gas liberated at ...

The volume of hydrogen gas liberated at STP when a current of 5.36 ampere is passed through dil. `H_(2)SO_(4)` for 5 hours will be

A

5.6 litres

B

11.2 litres

C

16.8 litres

D

22.4 litres

Text Solution

Verified by Experts

The correct Answer is:
B
Quantity of electricity passed `= 5.36 xx 5 xx 60 xx 60 s = 96480` coulombs
= 1 Faraday
`2H^(+) + 2e^(-) to H_(2)`
i.e., 2 Faraday , liberate `H_(2)` at STP = 22.4 litres
`therefore` 1 Faraday will liberate `H_(2)` at STP = 11.2 litres .
