Paper 3 SPM 2005 - Planning an Experiment


In paper 3 Chemistry SPM, a student is asked to plan an experiment based on the situation given. I have given this question to my students as an exercise. Most of the time, they would give me an wrong experiment plan. They planned experiment exactly the same as the experiment they carried out to investigate how the concentration of sodium thiosulphate affect its rate of reaction with sulphuric acid.
