Chemistry Sodium Thiosulpahte :: essays research papers

IntroductionOver the next few weeks I leave be doing several attempts of the same test that involves the reaction of sodium thiosulphate and hydrochloric acid, I will be closely watching the reaction and how wide in dole outs for the reactants to react. As yet I hurl non obstinate which of the several variables I will be changing. I also suggest to take results of the reaction down onto a table, which then will be transferred onto a line graph, which will show us the nature of the reaction.Variablesthither are five factors which affect the commit of a reaction, according to the hit theory temperature, concentration (of solution), pressure (in be adriftes), surface are (of solid reactants), and catalysts. I have chosen to investigate the effect of temperature on the reactants.AimTo discriminate the effects of a change in temperature and concentration we affect the rate of the reaction. The reaction that will be used isSodium Thiosulphate + Hydrochloric AcidNa2S2O3 (aq) + 2HCl (aq). proposalI am going to investigate what happens when sodium thiosulphate and Hydrochloric acid react.As I have done this experiment before I have a good understanding of what I need to so hopefully nothing will go wrong, also I will be going back to results and infor lustrelessnession I used before the experiment to make sure I am doing everything right. As I lack to have a fair test, so that I get unblemished results, I will make sure that all the main variables will stay the same all the way through the experiment, concentration of some(prenominal) solutions will be kept constant, as there is no gas the variable of pressure habit have an affect on this reaction, as I am apply no solids the variable of suface area wont be a problem, and finally as I am not using a catalyst it wont have an effect on the reaction. As well as these things being important there is a more important aspect that I will need to take into account and that is my own safety, and the safety of m y fellow pupils. To make sure I dont endanger myself I will be using the following apparatus1 thermometer1 beaker2 measuring cylinders1 conical flask1 tripod1 gauze1 heatproof mat1 stopwatch1 Bunsen burner1 pair of pair of tongs1 pair of gogglesTo make it easy to follow when brief graphs and when logging my data I will be using a table similar to this
