Aim: The aim of this investigation is to see how the concentration of sodium thiosulphate when added to hydrochloric acid affects the rate of the reaction. The reaction that takes place is Na2S2O3 (aq) + 2Hcl(aq) S (s)+ 2NaCl (aq) + So2 + H2O Sodium + Hydrochloric Sulphur + Sodium + Sulphur Thiosulphate Acid Chloride Dioxide Theory: In this experiment when the hydrochloric acid is added to the sodium thiosulphate, each of the liquids particles will collide with each other and bonds will be broken. When the concentration is higher the rate of reaction will be quicker, this is because when the concentration is higher there will be more particles and therefore bonds will be broken quicker as there will be more collisions. The rate of reaction is the speed at which, in this case the...
