Which salt is formed when sodium hydroxide reacts with nitric acid?
Answer and explanation
Correct answer: Sodium nitrate
This is a neutralisation reaction: an acid reacts with a base to form salt and water. The balanced equation is HNO₃ + NaOH → NaNO₃ + H₂O. Nitric acid supplies the nitrate ion, NO₃⁻, and sodium hydroxide supplies Na⁺; these ions combine in a 1:1 ratio to form sodium nitrate. Chloride, sulphate and carbonate are absent, so the other options cannot be formed.
