Question

Aluminium is more reactive than zinc.

• A. True
• B. False

Answer 1

The correct option is A True

• Reactivity series- It is a list of metals in the decreasing order of their reactivity.
• The topmost metal is the most reactive.
• The metal at the bottom is the least reactive.
• Aluminum is above zinc in the reactivity series, hence, it is more reactive than zinc.
• Aluminum can displace zinc in the zinc sulfate solution to form aluminum sulfate and zinc.
• $\underset{\mathrm{Aluminium}}{2\mathrm{Al}\left(\mathrm{s}\right)}+\underset{\mathrm{Zinc}\mathrm{sulphate}}{3{\mathrm{ZnSO}}_4\left(\mathrm{aq}\right)}\to \underset{\mathrm{Aluminium}\mathrm{sulphate}}{{\mathrm{Al}}_2{\left({\mathrm{SO}}_4\right)}_3\left(\mathrm{aq}\right)}+\underset{\mathrm{Zinc}}{3\mathrm{Zn}\left(\mathrm{s}\right)}$
• It is an example of a displacement reaction.
• Displacement reaction- A displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule.

Hence, the given statement is true.
