A current of `2.68A` is passed for one hour through an aqeous solution of `CuSO_(4)` using copper electrodes. Select the correct statement (s) from the following

A

increases in mass of cathode `= 3.174g`

B

decreases in mass of anode `= 3.174g`

C

no change in masses of electrode

D

the ratio between the change of masses of cathode and anode is `1:2`

Text Solution

Verified by Experts

The correct Answer is:
A, B
`Cd +2AgCI(s) rarr CuCI_(2)(aq) +Ag(s)`
`W = (E)/(96500) xx I xx t = (63.5 xx 2.68 xx 3600)/(2 xx 96500) = 3.174g`
