Rates of reaction - kinetics (A2)
Read our general notes on Risk Assessment
I did an investigation into the decomposition of hydrogen peroxide with potassium iodide using the iodine clock method. I used the method where you add sodium thiosulphate and time till blue colour appears, then add the same amount of sodium thiosulphate again and time till the blue colour reappears, and got ten readings. How do I interpret the results?
I suggest that you use the web to access the Google search engine (www.google.co.uk), type 'iodine clock' into the search pane and select UK sites only, you will come across numerous web sites which explain many different aspects of the iodine-clock experiments. The one from York University looks very useful.
Risk assessment
Before attempting any practical work based on the advice and suggestions on this website, you must do the following. Identify any hazards, assess the risks from these hazards, and then decide appropriate control measures to reduce the risks. You must have these approved by those in authority in your school or college laboratory. Do not rely on what is said on this website.
For further guidance see our tutorial on Risk Assessment.
