By Tom Pattle Contents Planning - Pg 2-7 Introduction - Pg 2 Background Knowledge - Pg 2-7 References - Pg 7 Prediction - Pg 8-10 Method - Pg 9 Apparatus - Pg 9-10 Fair test - Pg 10 Analysing evidence -Pg 11-12 Line graphs Conclusion - Pg 13 Evaluation - Pg 14-15 Plan Introduction The experiment is about the concentration of sodium thiosulphate affecting the rate of a chemical reaction when using hydrochloric acid. Here is the word equation for the chemicals that will be used: Sodium thiosulphate + hydrochloric sodium + water + sulphur + sulphur acid chloride dioxide Also, the symbol equation: Na2S2O3(aq) + 2HCl(aq) 2NaCl(aq) + H20(l) + SO2(g) + S(s) When this reaction takes place, a precipitate of insoluble sulphur will form. The time it takes for a cross to be blocked from view will be measured showing the cloudiness of the precipitate...
