Chemistry Coursework I am going to plan and carry out an investigation into one factor that affects the rate of a chemical reaction. That chemical reaction is going to be between sodium thiosulphate solution and dilute hydrochloric acid. To make this a fair test we will have to keep all variables the same except the one we area investigating. My variable that I am going to investigate is going to be the concentration of the sodium thiosulphate. Sodium thiosulphate solution and dilute hydrochloric acid produce a solid (seen as cloudiness). I am going to time how long it takes for the solid to block out a cross underneath a conical flask. From the time taken I can calculate the rate of reaction by working out 1/time (units s-1). Variables The variables that may have an affect on this experiment are: * The amount of sodium thiosulphate - the more sodium thiosulphate the more it is...
