The reaction between an acid and a base is known by which name?
Answer and explanation
Correct answer: Neutralisation
The reaction in which an acid reacts with a base is called neutralisation. The acidic effect of hydrogen ions and the basic effect of hydroxide ions are reduced because H+ and OH− combine to form water; the remaining ions generally form a salt. For example, HCl + NaOH → NaCl + H2O. Evaporation, filtration, and melting are physical processes, not acid-base reactions, so option A is correct.
