The cell reaction of the galvanic cell ...

The cell reaction of the galvanic cell
`Cu(s)|Cu^(2+)(aq)||Hg^(2+)(aq)|Hg(l)` is

A

`Hg+Cu^(2+)rarrHg^(2+)+cu`

B

`Hg+Cu^(2+)rarrCu^(+)+Hg^(+)`

C

`Cu+HgrarrCuG`

D

`Cu+Hg^(2+)rarrCu^(2+)Hg`

Text Solution

Verified by Experts

The correct Answer is:
A
Galvanic cell is `Cu(s) |Cu^(2+) (aq)||Hg^(2+) (aq) |Hg`
in the above cell oxidatin of copper and redcution of mercury takes place its cell reaction is written as
`Cu(s) +Hg^(2+) (aq) rarr Cu^(2+) (aq) +Hg`
