To a mixture containing places of zinc , copper and silver , ` 1 M H_(2)SO_(4)` was added . `H_(2)` gas was found to be evolved . Which of the metal/metals do you think has/have reacted ? Given
`E^(@) Zn|Zn^(2+) = + 0.76 V , E_(Cu^(2+) |Cu)^(@) = + 0.34 V` ,
`E_(Ag^(+) |Ag)^(@) = +0.80` V

A

All the metals

B

Only Zn

C

Both Zn and Cu

D

Only Ag

Text Solution

Verified by Experts

The correct Answer is:
B
Out of Zn ,Cu and Ag , only zinc has higher oxidation potential than `H_(2)` .
