Hydrochloric acid is what type of acid?
Answer and explanation
Correct answer: Strong acid
Hydrochloric acid, HCl, ionises almost completely in aqueous solution to form hydrogen or hydronium ions and chloride ions. Because its ionisation is nearly complete, it is classified as a strong acid, making option A correct. A strong base is an alkali such as sodium hydroxide, a neutral salt is a different chemical category, and neither weak-base option describes HCl.
