Chemistry Paper 3 WASSCE (SCHOOL CANDIDATES), 2019

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.
