The substatnce that will reduce Ag^(+) ...

The substatnce that will reduce ` Ag^(+)` to Ag but will not reduce `Ni^(2+) ` to Ni is.

A

`Al`

B

`Mg`

C

`Pb`

D

`Zn`

Text Solution

Verified by Experts

The correct Answer is:
C
This implies that ` Ag^(+) //Ag` has higher reduction potential than the substance while `Ni^(2+) //Ni` has lower reduction potential than the substance :
`Ag^(+) //Ag (0.80 V) gt Pb^(2+) //Pb (-0.13 V) gt Ni^(2+) //Ni (0.25 V)` .
