When a quantity of electricity is passed through `CuSO_(4)` solution, 0.16 g of copper gets deposited. If the same quantity of electricity is passed through acidulated water, then the volume of `H_(2)` liberated at STP will be : (given atomic weight of Cu=64)
A. `4 cm^(3)`
B. `56 cm^(3)`
C. `604 cm^(3)`
D. `8 cm^(3)`

Correct Answer - B
Number of equivalents of copper deposited `=0.16/32=0.005` Volume of `H_(2)` gas at STP `=11.2xx0.005`
`=0.056` litre `=56 cm^(3)`

Two faraday of electricity is passed through a solution of `CuSO_(4)`. The mass of copper deposited at the cthode is : (at mass of cu = 63.5 amu)

Correct Answer - C Equivalent mass of copper `=("Atomic mass")/("Valency")` `=63.5/2=31.75` Amount of copper deposited by 2 faraday `=2xx31.75` `=63.5 g`
