Science Coursework: Sodium Thiosulphate Experiment Introduction The aim of this experiment is to examine how a different amount of concentration effects the rate of reaction. First I will use my preliminary results to find a suitable time to use for the rest of my experiments. I will then determine how different amounts of concentration effect the rate of reaction. Na2 S2 O3 (l) + HCL (l) NaCL (aq) + SO2 (g) + S (s) Preliminary Plan In this part of the experiment I will be using 0.2 and 0.04 to determine a suitable rate of reaction to use for the main experiment. I will be using different volumes of each of the chemicals. I will be looking for a relatively short time so I will not be taking too long on the main experiment. I will place the chemicals into the beaker and then using a timer I will be seeing how long...
