Write a balanced chemical equation for each of the following reactions and also classify them.

Lead acetate solution is treated with dilute hydrochloric acid to form lead chloride and acetic acid solution.

The reaction is as follows:

Pb (CH₃COO)₂ + HCl → PbCl₂ + CH₃COOH

In the above reaction there are two acetate molecules on reactant side and only one molecule on product side. So let us balance it first.

Pb (CH₃COO)₂ + HCl → PbCl₂ + 2CH₃COOH

Now there are two chlorine molecules on product side and only one chlorine molecule on reactant side. So the overall balanced reaction can be written as follows:

Pb (CH₃COO)₂ + 2HCl → PbCl₂ + 2CH₃COOH

This reaction belongs to double displacement type of reaction as it involves exchange of ions.
