An investigation into how changing one variable influences the rate of reaction between sodium thiosulphate and dilute hydrochloric acid. Theory on which the investigation is based - collision theory Collisions are important in a reaction because in order for a reaction to occur the particles of sodium thiosulphate and hydrochloric acid must: * Collide with each other * The collision must have enough energy. If there is not enough energy in the collision the bonds of sodium thiosulphate will not break, therefore new bonds with the hydrogen cannot be formed. A successful collision requires old bonds to be broken and new ones formed. In our case this would involve Hydrogen molecules forming covalent bonds with the oxygen molecules leaving a precipitate of Sulphur. If our reaction were unsuccessful then no Sulphur would be formed. List of variables, which could affect the rate of reaction * The concentration of the dilute hydrochloric acid. * The concentration of sodium...
