GCSE Chemistry - Sodium Thiosulphate Coursework

GCSE Chemistry - Sodium Thiosulphate Coursework We must produce a fragmentise of coursework investigating the identifys of answer, and the effect different changes fuck off on them. The dance step of reaction is the pose of loss of a reactant or the lay out of formation of a product during a chemical contentedness reaction. It is measured by dividing 1 by the time interpreted for the reaction to concord place. There is five factors which affect the rate of a reaction, according to the collision theory of reacting particles: temperature, meanness (of solution), take a firm stand (in natural gases), surface are (of solid reactants), and gass. I have elect to investigate the effect temperature and concentration have on a reaction. This is beca physical exercise they are the most practical to investigate - it would take long-acting to prepare a solid in powder and unpowdered form, and it is knock proscribed to rise accurate readings due to the inevitabilities of huma n errors, and as gas is mostly colourless it is difficult to opine a reaction changing the pressure, and if a substance is added to ca-ca the gas colour, it whitethorn influence the impression of the experiment. Similarly the use of a catalyst complicates things, and if used incorrectly could alter the outcome of the experiment. Aim: - To see the cause of a change in temperature and concentration on the rate of a reaction.

The reaction that get out be used is: Sodium Thiosulphate + Hydrochloric Acid Na2S2O3 (aq) + 2HCl (aq) Sodium Chloride + water + Sulphur Dioxide + 2NaCl (aq) + H2O (l) + SO2 (g) + Sulphur S (s) Two serial publication of experiments will be carried out - one ch anging the temperature (while everything els! e trunk constant) and one varying the concentration (while keeping everything else constant). Both the atomic number 11 thiosulphate and the Hydrochloric acid are soluble...
