Given: `E^(@)(Cu^(2+) + Cu) = 0.337 V` and `E^(@)(Sn^(2+)|Sn) = -0.136`V. Which of the following statements is correct?

A

`Cu^(2+)` ions can be reduced by `H_(2)` (g)

B

Cu can be oxidized by `H^(+)`

C

`Sn^(2+)` ions can be reduced by `H_(2) (g)`

D

Cu can reduce `Sn^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
A
As `E_(Cu^(2+))^(@) to Cu= 0.337 V gt E_(H^(+)//H_(2))^(@)`
`therefore Cu^(2+)` can be reduced by `H_(2)`
