For this assignment, I investigated the cooling curves of stearic acid and paraffin wax to determine and compare their melting points. I carried out practical experiments by heating the substances until they melted and recording their temperatures at one-minute intervals as they cooled. I also calibrated different thermometers to determine which provided the most accurate and precise measurements. I presented my results using tables and cooling curve graphs and analysed the changes in temperatur...

This assignment investigates how titration and colorimetry can be used to determine the concentrations of unknown solutions. It covers standard-solution preparation, equipment calibration, risk assessments, experimental calculations, and an evaluation of the accuracy and reliability of each method. I met all the points and its Distinction level.
