Examiner insights
Official reportCommon pitfalls
- In empirical calculations, dividing raw percentage values directly by the smallest value instead of finding molar ratios first.
- Omitting state symbols when writing balanced equations for precipitation reactions.
Misconceptions
- Confusing basic oxides with acidic oxides, or failing to recognize zinc oxide as amphoteric.
- Identifying simple molecular substances as having ionic bonding due to misunderstandings of electronegativity differences.
Where marks are lost
- Failing to specify the correct oxidation states for transition metals in qualitative analysis names.
- Leaving empirical formulas in fractional ratio forms (e.g., C1H2.5 instead of C2H5).
- Neglecting to mention repeating experimental steps to achieve a constant mass in gravimetric water loss questions.
