Toby Hulbert An investigation into the effect of concentration on rate of reaction. Introduction The aim of this experiment is to determine the effects of different concentrations of sodium thiosulfate have on the rate of reaction between sodium thiosulfate and hydrochloric acid. Na2S2O3 (aq) + 2HCL(aq) ( S(s) + SO2 + H2O (l) + 2NaCl(aq) This is the reaction that takes place between Sodium thiosulfate and hydrochloric acid. The products of the reaction are sulfur as a solid, and sulfur oxide, sodium chloride and water as liquids. It is known that when the concentration of a reactant is increased, the rate of reaction is also increased. Therefore, this reaction can be used to determine the effect of change of concentration on rate by observing the rate of reaction at varied concentrations of sodium thiosulfate. To obtain my measurements I will time how long the reaction takes to occur in minutes at varied concentrations. The...
