I am doing a titration for my investigation on the sugar levels between fruit juice and real fruit. Can you tell me the calculations I need to do in order to get the levels of sugar in each once I have done the titration.

As for sugar content, you need to choose a reducing sugar as a standard to compare with your readings with, since these are the only types of sugar that can be detected using Benedict’s reagent (which I presume you are doing?) Glucose is usually regarded as the representative reducing sugar. You need to carry out a titration with a glucose solution of known concentration which you have made up.
 
Having titrated your standard solution, you can now compare your titre value with those obtained with the fruit samples and deduce the concentration of reducing sugar in each one.

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.
