Rates of Reaction Aim The aim of the experiment is to find out the how long it would take for Hydrochloric acid to react with Sodium Thiosulphate to make an opaque solution that will obscure the vision of seeing a cross drawn on a piece of paper below the solution. This will prove that, either, it will take longer for a chemical to react when heated or it will take slower for a chemical to react when heated. Equipment * 5cm cubed of Hydrochloric acid * 10cm cubed of Sodium Thiosulphate * 40cm cubed of water * Beaker * Paper with cross on * Bunsen burner * Safety Goggles * Heat proof mat. * Thermometer * Tripod * Gorse * Timer Prediction I think that the hotter the solution is, the quicker the reaction will take place. The colder the solution is, the slower the reaction will take place. This is because atoms within the reactants have to collide for a chemical reaction to take place. The...
