How long will a current of 1 ampere take for complete deposition of copper from 1 litre of `1NCuSO_(4).5H_(2)O` solution ?

A

`2 xx 26500` seconds

B

96500 seconds

C

`96500//4` seconds

D

9650 seconds

Text Solution

Verified by Experts

The correct Answer is:
B
1L of 1N of `CuSO_(4)` contains 31.75 g of Cu.
`[therefore NxxV="Equivalents"]`
`therefore` Number of coulombs Q =96,500
Also Q=It `therefore` t=`(Q)/(I) =(96,500)/(1)=96,500 s`.
