What is the reaction between an acid and a base called?
Answer and explanation
Correct answer: Neutralisation
A reaction between an acid and a base is called neutralisation because the acidic and basic effects are reduced when hydrogen ions and hydroxide ions combine. The essential ionic change is H⁺ + OH⁻ → H₂O; the remaining ions usually form a salt. Therefore option A is correct. Filtration separates solids, evaporation removes solvent, and melting changes physical state rather than describing an acid–base reaction.
