Without losing its concentration, `ZnCl_(2)` solution cannot be kept in contact with:

A

Au

B

Al

C

Pb

D

Ag

Text Solution

Verified by Experts

The correct Answer is:
B
In electrochemical series, Al is placed above Zn and all other are present below. Zn , So aluminium displaces zinc from `ZnCl_(2)` solution. Hence, it cannot be kept in contact with Al.
`2Al + 3ZnCl_(2) to 2ACl_(3) + 3Zn`
