Question

248. Reaction of acids and bases

(a) $\mathrm{NaOH}+{\mathrm{H}}_2{\mathrm{SO}}_4$

Answer 1

• When acids react with bases, they will from salt and water.
• This reaction is called a neutralization reaction.
• Sodium hydroxide reacts with sulphuric acid to form sodium sulfate and water.
• The chemical equation for the given reaction is as follows:

$\underset{\mathrm{Sodium}\mathrm{Hydroxide}}{2\mathrm{NaOH}\left(\mathrm{aq}\right)}+\underset{\mathrm{Sulphuric}\mathrm{acid}}{{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)}\to \underset{\mathrm{Sodium}\mathrm{Sulphate}}{{\mathrm{Na}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)}+\underset{\mathrm{Water}}{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$

• Sodium hydroxide and sulphuric acid both are strong base and strong acids respectively, hence, sodium sulfate is neutral in nature.
