Same amount of electric current is passed through solutions of `AgNO_3` and HCl. If 1.08 g of silver is obtained in the first case, the amount of hydrogen liberated at STP in the second case is

A

112 `cm^3`

B

22400 `cm^3`

C

224 `cm^3`

D

1.008 g

Text Solution

Verified by Experts

The correct Answer is:
A
Applying Faraday.s second law
`w_(H_2)/w_(Ag)=E_(H_2)/E_(Ag) implies w_(H_2) 1/108xx1.08=` 0.01 g
2 g `H_2` =22400 `cm^3` at STP 0.01 g `H_2 =22400/2xx0.01=112 cm^3`
