GCSE Chemistry - Sodium Thiosulphate Coursework

GCSE Chemistry - Sodium Thiosulphate Coursework We moldiness produce a sepa lay of coursework investigating the identifys of answer, and the consequence unalike changes start on them. The govern of reaction is the rate of harm of a reactant or the rate of formation of a crossing during a chemical import reaction. It is measured by dividing 1 by the time memorisen for the reaction to take place. at that place is five factors which affect the rate of a reaction, according to the clash theory of reacting particles: temperature, meanness (of solution), insisting (in natural gases), surface ar (of solid reactants), and gass. I have elect to investigate the effect temperature and denseness have on a reaction. This is beca call they are the closely practical to investigate - it would take long-acting to prepare a solid in pulverized and unpowdered form, and it is knock proscribed to maintain accurate readings due to the inevitabilities of charitable errors, and as gas is loosely colourless it is difficult to try a reaction changing the pressure, and if a substance is added to allow the gas colour, it whitethorn wreak the burden of the experiment. Similarly the use of a catalyst complicates things, and if utilize 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 go out be used is: Sodium Thiosulphate + Hydrochloric Acid Na2S2O3 (aq) + 2HCl (aq) Sodium Chloride + irrigate + process Dioxide + 2NaCl (aq) + H2O (l) + SO2 (g) + Sulphur S (s) Two series of experiments will be carried out - unmatched(a) changing the temperature (while everything else remains constant) and one varying the concentration (while belongings everything else constant). Both the sodium thiosulphate and the Hydrochloric stinging are soluble...
