James Hadley 11m PLANNING Aim: My aim is to investigate the effect of the change of temperature on the rate of reaction between sodium thiosulphate and hydrochloric acid. Method: First of all I will need to set up my apparatus, which can be seen on the diagram. In each experiment I will first of all need to get the sodium thiosulphate to the temperature needed, which will be 20 degrees C, 30 degrees C, 40 degrees C, 50 degrees C, and 60 degrees C. Then I will need to put the beaker onto a piece of paper with a cross drawn on it, then I will add the hydrochloric acid to the sodium thiosulphate, and time how long it takes until I can no longer see the cross on the paper.
