What examiners said
Some candidates gained credit. This was a demanding question and answers often included mistakes such as Fe2, and I3 or showed ionic charges. Credit is not awarded for balancing an equation if formulae are incorrect.
— Examiner report, May/June 2025, 0653/41 Q5(c) (Cambridge)
This question tested the ability to design a table to present qualitative data. Most candidates gave a table which showed which solutions were mixed and described the related observations. The best answers included headings such as ‘solutions mixed’ and ‘observations on mixing’. However, some candidates drew tables without headings. Others included a column for ‘solutions’, listing H, J, K and L,...
