What type of acid is hydrochloric acid considered?
Answer and explanation
Correct answer: Strong acid
Hydrochloric acid, HCl, is classified as a strong acid because it ionises almost completely in water: HCl → H⁺ + Cl⁻. This produces a high concentration of hydrogen ions and gives the solution strongly acidic properties. Therefore option A is correct. A weak base, neutral salt, and alkali describe different chemical categories and cannot correctly classify hydrochloric acid.
