Answer:

The balanced single displacement reaction between aluminum and copper sulphate is as follows.

$2Al(s)+3CuSO_{4}(aq)\rightarrow Al_{2}(SO_{4})_{3}(aq)+3Cu(s)$

Explanation:

The given ions are as follows.

$Al^{3+}$ - Aluminium ion and copper sulfate ion.

Single displacement reaction occurs one element replaces another element.

Hence, the balanced chemical reaction is as follows.

$2Al(s)+3CuSO_{4}(aq)\rightarrow Al_{2}(SO_{4})_{3}(aq)+3Cu(s)$

Oxidation half reaction:

$Al\rightarrow Al^{3+}+3e^{-}$

Aluminium loses three electrons.

Reduction half reaction:

$Cu^{2+}+2e^{-}\rightarrow Cu(s)$

Copper gain three electrons.
