State with equations, what happens when (any five) :
(7) Al powder is added to copper sulphate solution.

Text Solution

Verified by Experts

When Al is added to an aqueous solution of `CuSO_(4)`, copper (less electropositive and placed below Al in the electrochemical series) is precipitated and aluminium sulphate thus formed dissolves in aqueous solution.
`2Al+3CuSO_(4)rarr 3Cu darr+Al_(2)(SO_(4))_(3)`
