Introduction
Over the next few weeks I will be doing several attempts of the same experiment that involves the reaction of sodium thiosulphate and hydrochloric acid, I will be closely watching the reaction and how long in takes for the reactants to react. As yet I have not decided 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.
Variables
There are five factors which affect the rate of a reaction, according to the collision theory: temperature, concentration (of solution), pressure (in gases), surface are (of solid reactants), and catalysts. I have chosen to investigate the effect of temperature on the reactants.
Aim
To see the effects of a change in temperature and concentration we affect the rate of the reaction. The reaction that will be used is:
Sodium Thiosulphate + Hydrochloric Acid
Na2S2O3 (aq)......
