Rate of Reaction Aim: To watch and keep record of the effects of a change in concentration on the rate of reaction. Word equation: Hydrochloric Acid + sodium thiosulphate --> Sulphur dioxide + Sodium Chloride + water 2HCl + Na2S203 --> 2Na + SO2 + H2O Plan: In this experiment I will be testing the rate of reaction of Hydrochloric acid and Sodium Thiosulphate. The rate of reaction tells us how quickly a reaction happens, so I will increase the concentration of the hydrochloric acid each time I do the experiment, adding 1/4 of distilled water to 2 molars of the acid therefore providing us with the concentrations 2, 1.5,1,0.5 and finally 0 to react with the acid. I will do a pretest first to see if the amounts of acid and Sodium Thiosulphate work and to see if there won't be any anomalous results. Equipment: Diagram of equipment: 2x beaker 4x conical flask 2x measuring...
