The position of some metals in the electrochemical series in decreasing electropositive character is given as Mg Al Zn Cu Ag. What will happen if a copper spoon is used to stir a solution of aluminium nitrate?

Question

The position of some metals in the electrochemical series in decreasing electropositive character is given as Mg > Al > Zn > Cu > Ag. What will happen if a copper spoon is used to stir a solution of aluminium nitrate? (A) The spoon will get coated with aluminium (B) An alloy of copper and aluminium is formed (C) The solution becomes blue (D) There is no reaction

The spoon will get coated with aluminium

An alloy of copper and aluminium is formed

The solution becomes blue

There is no reaction

Reduction potential of copper is more than aluminium. Thus, there is no reaction.
