Question

Write a balanced chemical equation for the given reaction and also classify them: Lead acetate solution is treated with dilute hydrochloric acid to form lead chloride and acetic acid solution.

Answer 1

Balanced chemical equation:

• A balanced chemical equation is an equation where the number of atoms in the reactant and the product side should be an equal number.
• It can be balanced by using coefficients in front of reactant or product species..

Chemical Reaction:

• The reaction of lead acetate solution with dilute hydrochloric acid results in the formation of lead chloride and acetic acid.
• The balanced equation is

$\mathrm{Pb}{\left({\mathrm{CH}}_3\mathrm{COO}\right)}_2\left(\mathrm{aq}\right)+2\mathrm{HCI}\left(\mathrm{aq}\right)\to {\mathrm{PbCl}}_2\left(\mathrm{s}\right)+2{\mathrm{CH}}_3\mathrm{COOH}\left(\mathrm{aq}\right)$

• The above reaction is an example of a double displacement reaction.

Double displacement reaction

• Two atoms or a group of atoms shift positions to generate new compounds in a double displacement process.
• The double displacement reaction is represented in general as,

$\mathrm{AB}+\mathrm{CD}\to \mathrm{AC}+\mathrm{BD}$
