Step 1
A) Acid Y is completely ionised in solution.
Answer
This statement is incorrect because if acid Y were completely ionised, it would be classified as a strong acid rather than a weak acid. Since acid X is described as a stronger acid than acid Y, it implies that acid Y does not dissociate fully in solution. Rather, both acids, being monoprotic weak acids, will only partially ionise, meaning that acid Y is not completely ionised in solution.
