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 aluminium and copper is formed
• C. The solution becomes blue
• D. There is no reaction

Answer 1

The correct option is D There is no reaction

According to the given electrochemical series, Al is having more electropositive character than that of Cu, that means Al is more reactive than that of Cu and easily replace Cu from its solution, so, when a copper spoon is used to stir aluminium nitrate solution then no reaction occurs.
