Planning: My aim of the coursework is to find out will concentration of a solution affect the rates of the reaction. As a best way of doing it, I am going to use hydrochloric acid and sodium thiosulphate to react with each other. Sodium thiosulphate + hydrochloric acid ---> sodium chloride + sulphur+ sulphur dioxide + water Na2S2O2(aq) + 2HCL(aq) ---> 2Nacl(aq) + S(s) + SO2(g) + H2O(I) The apparatus I am going to use will be: -Sodium thiosulphate -Hydrochloric acid -Stop Clock -Measuring Cylinder -Conical Flask -Thermometer -Paper (with cross drawing over) What I am going to do is to use the product sulphur and measure how long it takes for the cross disappear by increasing its concentration. I am going to do that in this order: -Put 20ml of hydrochloric acid in a conical flask under a cross -Put 20ml of Sodium Thiosulphate in the same flask -Mix them in a conical flask -Take the amount of time when u can't see the cross using...
