Read our general notes on Risk Assessment
Please could you tell me the difference between normal Benedicts solution and quantitive Benedicts solution.
If you refer to the Nuffield Chemistry 'Food Science' students book, page 11, experiment 2.7a, you will see that quantitative Benedict's solution contains potassium thiocyanate as well as copper(II) sulphate, and it tells you what difference it makes. If the precipitate was red, it might be harder to recognise the end point of the titration. I'm assuming that your question arises from this experiment.

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.
