Introduction

Lewis Brend Friday. 28 September 2001 Rates of Reaction Aim: To find out how temperature will effect the rate of reaction between sodium thiosulphate and hydrochloric acid. Apparatus: Stop-clock Conical flask Thermometer Beaker Tripod Gauze Bunsen Burner Paper with a cross on it Safety Specs Heat Mat Measuring Cylinders Sodium Thiosulphate Hydrochloric Acid Prediction: My prediction is that the ...read more.

Middle

Light the Bunsen burner and fill a beaker with 100ml of water, then measure 20ml in a measuring cylinder and put into a conical flask. Put the conical flask in with the beaker. Keep checking the temperature by using a thermometer. ...read more.

Conclusion

Once it has gone this colour stop the sop-clock and take note of the time. Then do this for the rest of the temperatures. This will be made a fair test by not stirring the acids and by doing the exact same procedure to the other tests. Doing this will make it a fair test. Results: Temperature Time Taken 20� 131.16 30� 82.63 40� 31.02 50� 31.16 60� 24.55 70� 15.95 ...read more.

    Phosphoric acid reacts the slowest, therefore I needed to increase the activation energy for it to react with the magnesium. Sulphuric acid is the fastest to react, as it has the lowest activation energy there needs not much energy for it to react with the magnesium molecules, and hydrochloric acid that reacts somewhere in-between.
