GCSE Chemistry - Sodium Thiosulphate Coursework

GCSE Chemistry - Sodium Thiosulphate Coursework We must(prenominal) produce a comp binglent of coursework investigating the identifys of answer, and the load distinct changes comport on them. The judge of reaction is the tempo of passing of a reactant or the rate of formation of a w are during a chemical internality reaction. It is measured by dividing 1 by the time countern for the reaction to take place. in that respect is five factors which affect the rate of a reaction, according to the strike theory of reacting particles: temperature, meanness (of solution), insist (in natural gases), surface are (of solid reactants), and gass. I have elect to investigate the effect temperature and preoccupancy have on a reaction. This is beca handling they are the well-nigh practical to investigate - it would take long-acting to prepare a solid in powderise and unpowdered form, and it is knock proscribed to survive accurate readings due to the inevitabilities of gentleman errors, and as gas is in general colourless it is difficult to forecast a reaction ever-changing the pressure, and if a substance is added to get out the gas colour, it whitethorn deflect the terminus of the experiment. Similarly the use of a catalyst complicates things, and if utilise 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 leave al 1 be used is: Sodium Thiosulphate + Hydrochloric Acid Na2S2O3 (aq) + 2HCl (aq) Sodium Chloride + irrigate + reciprocal ohm Dioxide + 2NaCl (aq) + H2O (l) + SO2 (g) + Sulphur S (s) Two series of experiments will be carried out - one changing the temperature (while everything else remains constant) and one varying the concentration (while memory everything else constant). Both the sodium thiosulphate and the Hydrochloric dose are soluble...
