A) Au
B) Al
C) Pb
D) Ag
Correct Answer: B
Solution :
In electrochemical series Al is placed above Zn and all others are present below Zn. So, aluminium displaces zinc from \[ZnC{{l}_{2}}\] solution. Hence, it cannot keep in contact with Al \[2Al+3ZnC{{l}_{2}}\xrightarrow[{}]{{}}2AlC{{l}_{3}}+3Zn\]You need to login to perform this action.
