Question

Neutralisation reaction between acids and bases are ________________________ reactions.

Answer 1

• A neutralization reaction is a type of chemical reaction in which an acid reacts with a base to form salt and water.
• It is a kind of double displacement reaction.
• The product salt formed from the neutralization reaction always contains cation from the base and anion from the acid.
• They are generally represented as : $\mathrm{Acid}+\mathrm{Base}\to \mathrm{Salt}+\mathrm{Water}$
• Example: The base $\mathrm{Sodium}\mathrm{hydroxide}\left(\mathrm{NaOH}\right)$ react with acid $\mathrm{Hydrochloric}\mathrm{acid}\left(\mathrm{HCl}\right)$ to form the salt $\mathrm{Sodium}\mathrm{chloride}\left(\mathrm{NaCl}\right)$ and water $\left({\mathrm{H}}_2\mathrm{O}\right)$.

Thus, Neutralisation reactions between acids and bases are double displacement reactions.
