The weight of copper (At wt = 63.5) displaced by a quantity of electricity which displaces 5600 ml of `O_(2)` at STP will be :-

A

63.5 g

B

31.5 g

C

15.875 g

D

127 g

Text Solution

Verified by Experts

The correct Answer is:
B
According to faraday's second law
`(W_(Cu))/(E_(Cu))=(W_(O2))/(E_(O2))rArrW_(w)=31.75 g`
