Select the correct statements if 9.65 A ...

Select the correct statements if `9.65 A` current is passed for 1 hour through the cell `:`
`Ag|Ag^(o+)(1M)||Cu^(2+)(1M)|Cu`.

A

`Ag` will oxidize to `Ag^(o+)` and new `[Ag^(o+)]=1.36M`.

B

`Ag^(o+) ` will reduce to `Ag` and new `[Ag^(o+)]=0.64M`

C

`Cu^(2+)` will reduce to `Cu` and new `[Cu^(2+)]=0.82M`.

D

`Cu` will oxidize to `Cu^(2+)` and new `[Cu^(2+)]=0.82M`.

Text Solution

Verified by Experts

The correct Answer is:
a,c

`(W)/(E_(w))=(It)/(96500)=(9.65xx3600)/(96500)`
`=0.36eq of Ag^(o+)`
`=0.36 eq of Cu2^(@+)`
`=0.36 mol es of Ag^(o+)`
`=0.18 mol e of Cu^(2+)`
Now, `Ag`. Will oxidize to `Ag^(o+)` and `Cu^(2+)` will reduce to `Cu`.
