I am going to investigate the reaction between thiosulphate and hydrochloric acid. Background information. Sodium Thiosulphate is made up of Sodium, Sulphur and Oxygen (NaSO). Hydrochloric acid is made up of Hydrogen and Chlorine (HCl). Both liquids are clear. The equation for this is: Planning. There four factors that can affect the rates of reaction these are: * Temperature, * Concentration, * Surface area, * The use of a catalyst. At low temperatures, particles of reacting substances do not have much energy. When the substances are heated, the particles take in energy. This causes them to move faster, and therefore they collide more often with a greater chance of a successful collision. This causes the rate of reaction to increase. Low temperature High temperature A reaction can be made to go faster or slower by changing the concentration of a reactant. If a reactant has a great concentration then there are more particle's involved in the reaction therefore there is more...
