Question

Which of the following acid and base reacts to form sodium chloride?

• A. Sulphuric acid and sodium hydroxide
• B. Hydrochloric acid and sodium hydroxide
• C. Sulphuric acid and sodium carbonate
• D. Acetic acid and sodium hydroxide

Answer 1

The correct option is B Hydrochloric acid and sodium hydroxide

A neutralisation reaction occurs between the acid and a base to form salt and water. Sodium chloride is a neutral salt formed from a neutralisation reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH). The reaction involved is given below:

$\text{HCl (aq)}+\text{NaOH (aq)}\to \text{NaCl (aq)}+{\text{H}}_2\text{O (l)}$
