When same quantity of electricuty is passed through aqueous `AgNO_(3)` and `H_(2)SO_(4)` solutions connected in series, `5.4xx10^(-2) g` of `H_(2)` is liberated. What is the mass of silver (in grams) deposited? (Equivalent weight of hydrogen `=1008`, silver `=108`)

A

54

B

0.54

C

5.4

D

10.8

Text Solution

Verified by Experts

The correct Answer is:
C
According to Faraday's second law of electrolysis,
`("Weight of silver deposited")/("Weight of hydrogen liberated")=("Eq. wt. of silver")/("Eq. wt. of hydrogen")`
`w/(5.04xx10^(-2))=108/1.008`
`w=(108xx5.04xx10^(-2))/1.008=5.4 g`
