Between equal concentration solutions of vinegar acid and hydrochloric acid, which can produce more ions?
Answer and explanation
Correct answer: Hydrochloric acid
At equal formal concentration, the amount of ionisation determines how many ions are produced in solution. Hydrochloric acid is treated as a strong acid and ionises almost completely, giving H₃O⁺ and Cl⁻ ions. Acetic acid in vinegar is weak and ionises only partially, so fewer particles form ions. Both do produce ions, but not equally under these conditions. Hence hydrochloric acid, option B, can produce more ions.
