Plan: I am going to investigate how temperature affects the rate of the reaction of sodium thiosulphate and hydrochloric acid. WORD EQUATION Sodium thiosulphate + Hydrochloric acid Sodium chloride (salt) + Sulphur + Water + Sulphur dioxide CHEMICAL EQUATION Na2S2O3 + 2HCl 2NaCl + S + H2O + SO2 The temperature of the sodium thiosulphate will be changed by heating the solution to a known temperature. The concentration of the acid remains unchanged. I am going to do one experiment, changing the temperature of the sodium thiosulphate. This is how they will be done. (Fig.1) (Fig.1a) 廈eat Sodium thiosulphate in electric water bath to desired temperature 感our 50 cm3 of Sodium thiosulphate into a beaker then put on the paper with a cross 感our 5cm3 of hydrochloric acid in to a cylinder 感our hydrochloric acid into the beaker with the sodium thiosulphate 嫂s soon as the two substances are mixed together, the stopwatch will start timing and it will stop when the cross is obscured 愛ecord results 慌ash out the flask thoroughly 愛epeat experiment again for 2nd results 愁hen...
