Which is the balanced single displacement reaction between Aluminum (Al3+) and Copper Sulfate (Cu2+(SO4)2-)

Aliun [14]

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.

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

<u>Oxidation half reaction:</u>

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

Aluminium loses three electrons.

<u>Reduction half reaction:</u>

<u> $Cu^{2+}+2e^{-}\rightarrow Cu(s)$ </u>

Copper gain three electrons.
