What examiners said
The negative numbers made this more demanding for candidates. Quite a few gave –253 or –259 and others did not include the negative sign in their answers.
— Examiner report, May/June 2025, 0973/31 Q5(b) (Cambridge)
A significant number of candidates had the idea of a pop noise being made but couldn’t indicate the test that led to this noise, often confusing it with the test for oxygen.
— Examiner report, May/June 2025, 0973/31 Q5(d) (Cambridge)
Candidates were generally not specific enough in their response to this question, either not including the relevant temperature or the idea that only pure water boils at this temperature. Candidates often had the idea of boiling the water and then looking for a residue, or using a pH indicator.
