The positive value of the standard elect...

The positive value of the standard electrode potential of `Cu^(2+)//Cu` indicates that.......

A

this redox couple is a stronger reducing agent than the `H^(+)//H_(2)` couple

B

this redox displace `H_(2)` from acid

C

Cu cannot displace `H_(2)` from acid

D

Cu cannot displace `H_(2)` from acid

Text Solution

Verified by Experts

Lesser the `E^(@)` value of redox couple higher the reducing power.
`Cu^(2+)+2e^(-)rarrCu`
`2H^(+)+2e^(-)rarrH_(2)`
Since `2H^(@)//H_(2)` has lesser SRP than `Cu^(2+)//Cu` redox couple. Therefore.
(i) This redox couple is a stornger oxidising agent than `H^(+)//H_(2)`.
Hence, b and d are correct.
