A current of 0.5 A is passed through a solution of `CuSO_(4)` for 20 min by using platinum electrodes. (2) What volume of `O_(2)` at STP will be evolved at the anode?

Text Solution

Verified by Experts

600C of electricity will liberate `(8)/(32)xx(600)/(96500)=1.554xx10^(-3)" mol of "O_(2)" at the anode."`
At STP, 1 mol of `O_(2)` gas occupies 22.4 L.
and, `1.554xx10^(-3)` mol of `O_(2)` gas occupies
`1.554xx10^(-3)xx22.4L=34.8mL.`
