GivenE(Ag^(+)//Ag^(@) = 0.80V, E(Mg^(2+)...

Given`E_(Ag^(+)//Ag^(@) = 0.80V`, `E_(Mg^(2+)//Mg^(@) =-2.37V`,
`E_(Cu^(2+)//Cu) = 0.34V` , `E_(Hg_(2)^(2+)//(Hg))^(@) = 0.79V`
Which of the following statement is are incorrect ?

A

`Ag^(+)` can be reduced by `H_(2)`

B

`Ag` can oxidise `H_(2)` into `H^(+)`

C

`Zn^(2+)` can be reduced by `H_(2)`

D

Ag can reduce `Zn^(2+)` ion.

Text Solution

Verified by Experts

The correct Answer is:
A
Zinc has lower red pot, than hydrogen and hence can be reduced. Ag has more reduction potential so it is reduced easily.
