Chemistry Sodium Thiosulpahte :: essays research papers

IntroductionOver the next few weeks I allow be doing several attempts of the same experiment that involves the reception of sodium thiosulphate and hydrochloric acid, I impart be closely watching the reaction and how long in takes for the reactants to react. As yet I have not distinguishable which of the several variables I will be changing. I also aim 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.VariablesThere are five factors which affect the rate of a reaction, according to the collision theory temperature, absorption (of solution), pressure (in gases), surface are (of solid reactants), and accelerators. I have chosen to canvas the effect of temperature on the reactants.AimTo see the effects of a lurch in temperature and concentration we affect the rate of the reaction. The reaction that will be used isSodium Thiosulphate + Hydrochloric AcidNa2S2O3 (aq) + 2HCl (aq).PlanI am going to investigate what happens when sodium thiosulphate and Hydrochloric acid react.As I have done this experiment in the lead I have a good understanding of what I privation to so hopefully nothing will go wrong, also I will be going back to results and information I used before the experiment to make sure I am doing everything right. As I want to have a fair test, so that I get blameless results, I will make sure that all the main variables will stay the same all the way through the experiment, concentration of both solutions will be kept constant, as there is no gas the variable of pressure wont have an affect on this reaction, as I am using 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 my fellow pupils. To make sure I dont end anger myself I will be using the following apparatus1 thermometer1 beaker2 measuring cylinders1 conical flask1 tripod1 gauze1 heatproof mat1 stopwatch1 Bunsen burner1 pair of tongs1 pair of gogglesTo make it easy to follow when muster graphs and when logging my data I will be using a table similar to this
