Question

Sodium hydroxide and hydrochloric acid neutralise each other and form salt and water.

• A. True
• B. False

Answer 1

The correct option is A True

Neutralisation Reaction

1. When a strong acid combines with a strong base, It gives out salt and water called a neutralisation reaction.
2. When a strong acid-like hydrochloric acid ($\mathrm{HCl}$) reacts with a strong base $\left(\mathrm{NaOH}\right)$ the outcome is salt ($\mathrm{NaCl}$) and water.
3. Reaction involved: $\underset{\mathrm{Hydrochloric}\mathrm{acid}}{\mathrm{HCl}\left(\mathrm{aq}\right)}+\underset{\mathrm{Sodium}\mathrm{Hydroxide}}{\mathrm{NaOH}\left(\mathrm{aq}\right)}\to \underset{\mathrm{Sodium}\mathrm{Chloride}}{\mathrm{NaCl}\left(\mathrm{s}\right)}+\underset{\mathrm{Water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{aq}\right)}$

Therefore, sodium hydroxide reacts with hydrochloric acid to form salt and water. The above statement is true.
