The difference between a strong acid and a weak acid is mainly based on what?
Answer and explanation
Correct answer: Degree of ionisation in water
Acid strength is governed mainly by the extent of ionisation in water. A strong acid, such as hydrochloric acid in school-level treatment, ionises nearly completely and produces a high proportion of H₃O⁺ ions. A weak acid, such as acetic acid, ionises only partially and establishes an equilibrium. Colour, container size, and smell do not define strength. Therefore, the scientifically correct choice is option B.
