Consider the following reactions:
`Zn(s)+cu^(2+)(aq)rarrZn^(2+) (aq)+Cu(s)`
With reference to the above reaction which one of the following is correct statement:

A

Zn is reduced to `Zn^(2+)` ions

B

Zn is oxidized to `Zn^(2+)` ions

C

`Cu^(2+)` ions oxidized to Cu

D

`Zn^(2+)` ions are oxidized to Zn

Text Solution

Verified by Experts

The correct Answer is:
B

`Zn + Cu^(2+) rarr Zn^(2+) + Cu`. In this reaction Zn loses 2 electrons i.e., it get oxidized.
