Sodium Thiosulphate Rates of Reactions During this research I am tone ending to study Sodium Thiosulphate the rates of Reactions and which changes result affect this rate. A rate of reply is when a reactant is lost or a new product is formed during a Chemical reaction. I am expiration to investigate the effect of Concentration by mixing Sodium Thiosulphate, Hydrochloric Acid and H2O (Water) until the reaction takes cope and the mixture goes cloudy and The newspaper beneath the flask impale no longer be read. Both the Sodium Thiosulphate and the Hydrochloric sulphurous are soluble in water, so the Concentration of all can be changed. However I am pass to use Varying bills of Sodium Thiosulphate acid and H2O save I will keep The amount of Hydrochloric Acid constant. This is ponderous factor to Investigate as the readings are recorded by human reactions, which Could differ due to the inevitabilities of a human error.

work to the collision theory of reacting particles there are five motley factors, which could affect this rate of reaction, these are: * Temperature * The concentration of the solution * The pressures of the gases * The have it off out area if using solid reactants * Catalysts I prophesy that when I use the highest concentration of Sodium Thiosulphate the reaction will draw much faster than when I use a trim down concentration. I predict that there whitethorn be a pattern to the results because the concentration is decreasing in equal amounts and therefore the rate of reaction may do too. This is because for a reaction to ta! ke place particles have to clash with an different solely only a small dowery of these collisions result in a reaction. If I increase the amount of particles then they are also more likely to jolt with each other and therefore the reaction should also blow over much faster, level off though the amount of thriving collisions remain the same.
