Introduction Erewrwe Dsfsdfdsfsd Aim: Find out the effect of concentration on reaction rates between chemicals. The equation to this is as follows: Sodium +Hydrochloric Sodium +Sulphur +Sulphur +water Thiosulphate Acid Chloride Dioxide Na2S2O3 (aq) + HCL (aq) 2NaCl(aq)+ S(s) +SO2(g) + H2o(l) This reaction usually produces a yellow precipitate. We place the reaction mixture on a paper with a black cross drawn on it. When the cross is completely obscured, the reaction will have finished. The time taken for this to happen is the measure of the rate of reaction. We must do this several times, and change the concentration of sodium thiosulphate. The rate of reaction is a measure of the change which happens during a reaction in a single unit of time. The rate of reaction is the rate of loss of a reactant or the rate of formation of a product during a chemical reaction. It is measured by dividing 1...
