Practical investigations
Read our general notes on Risk Assessment
I am currently Advanced Higher Chemistry in Scotland and am about to start my investigation i would like to do a quantitative determination of vitamin C in different brand tablets or an experiment involving esters. Could you please suggest some investigations involving these topics.
Ulex writes: What a very interesting idea. You will find that the Nuffield Advanced Chemistry Special Study ‘Food Science’ has a very useful experiment which you could adapt. In the Study, the experiment is used to estimate the Vitamin C content of cabbage but I am sure the method could be adapted to work with tablets. The details are on p.11 of the student’s booklet, Experiment 2.7b. Vitamin C is also used as a flour improver; would there be any future in trying to find out if there is a measureable amount in ordinary domestic flour and also in flour for breadmaking ?
Esters might be a bit harder to investigate, especially if you want quantitative measurements.
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.
