Rates of reaction - kinetics (A2)
Read our general notes on Risk Assessment
For my chemistry investigation I am researching the catalytic decomposition of hydrogen peroxide, using a variety of catalysts to find the best one. My first experiment is a control, no catalyst being used. I am, however, having a few probelms with the timescale. Originally I thought one hour at ten minute intervals but in my preliminary test no change had occurred. I've changed that to two hours at 15 minute intervals. My question is without a catalyst, what is the time for hydrogen peroxide to decompose?

The answer is slowly - days rather than hours - at room temperature, depending on the presence of impurities that may act as catalysts. Your control is therefore that there is no detectable change in the time you have for your experiments with catalysts.
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.
