Question

Write the balanced chemical equations for the given reactions: Sodium carbonate on reaction with hydrochloric acid in equal molar concentration gives sodium chloride and sodium hydrogen carbonate.

Answer 1

Balanced chemical equation: A balanced chemical equation is the representation of a chemical reaction in which the number of atoms of each element is the same on both the reactant and product sides.

Reaction of Sodium carbonate with Hydrochloric acid:

• When Sodium carbonate reacts with Hydrochloric acid, it gives Sodium chloride salt and Sodium hydrogen carbonate.
• It is an acid-base reaction where sodium carbonate serves as a base while hydrochloric acid is an acid that leads to the formation of a salt. This reaction can also be known as the Neutralisation reaction.
• The chemical equation can be depicted as:

$\underset{\mathrm{Sodium}\mathrm{carbonate}}{{\mathrm{Na}}_2{\mathrm{CO}}_3\left(\mathrm{s}\right)}+\underset{\mathrm{Hydrochloric}\mathrm{acid}}{\mathrm{HCl}\left(\mathrm{aq}\right)}\to \underset{\mathrm{Sodium}\mathrm{chloride}}{\mathrm{NaCl}\left(\mathrm{aq}\right)}+\underset{\mathrm{Sodium}\mathrm{bicarbonate}}{{\mathrm{NaHCO}}_3\left(\mathrm{aq}\right)}$
