Combine each side and then balance the whole equation. Al+HCl=AlCl3+H^+
Aneli [31]

Answer:

2Al + 6 HCl ---> 2AlCl_3 + 3 H_2

Explanation:

The valency of aluminium is +3 while the valency of chlorine is -1

we will first write the half reactions

Half oxidation reaction

Al -----> Al^{3+} + 3^{e-}\\2H^+ 2e^- ----> H_2\\Cl + e^- -----> Cl^-

Now will write the complete equation-

Al + HCl -----> AlCl_3 + H_2

The balanced equation would be

2Al + 6 HCl ---> 2AlCl_3 + 3 H_2
