CANDIDATES’ STRENGTHS
Candidates’ strengths in the paper were evident in the following areas:
- majority of the candidates were able to carry out titrations and obtained concordant titre values;
- a good number of the candidates were able to calculate average titre value;
- majority of the candidates were able to present the experimental results in correct format;
- identification of the gas evolved during test tube reactions;
- ability to state the mathematical relationship between molar mass, mass concentration and molar concentration.
- determination of percentage purity;
- ability to state the unit of average titre value.
