Question

A. Lower ionisation results in a higher pH. - correct exam wording for HT only
B. Wrong exam wording: confuses HT only with a nearby Unit 4.4 chemical change idea
C. Wrong particle check: uses the wrong ion, electrode, acid-base term, or product for Strong and weak acids (HT only)
D. Wrong reaction link: does not support (HT only) Describe a weak acid as only partially ionised in aqueous solution

Answer

The correct option is Lower ionisation results in a higher pH. - correct exam wording for HT only.

Explanation

The correct option is "Lower ionisation results in a higher pH. - correct exam wording for HT only" because it supports the approved learning objective: (HT only) Describe a weak acid as only partially ionised in aqueous solution. The other options are incorrect or weaker because they are vague, use the wrong Chemistry context, or do not clearly explain the answer for Strong and weak acids (HT only).

Common mistake

Weak Acid Misconception

Students often think that weak acids do not ionise at all in solution.

Emphasize that weak acids do ionise, but only partially, meaning some molecules remain un-ionised in solution.
