In lab, we have to design an experiment that determines the concentration of sucrose in a solution.  We will receive the solution in class on Wed, right now we only need to design the experiment and tell the instructor what we will need to determine the concentration.

I want to get a good grade, but I don't want to have someone else do the work for me.  Can someone point me in the right direction?

I think I would first determine if sucrose is present by a benedicts test.  I am not sure at all how to determine the concentration.

Thanks!

Well, sucrose is NOT a reducing sugar so it will not react at all with Benedict's Reagent, so that experiment will have to be nixed.    However, in an acidic environment sucrose will decompose into glucose and fructose.  Glucose and Fructose are both reducing sugars, so they will both react with Benedict's Reagent.  

Take a look at this site, and you will find everything you need.  http://encyclopedia.thefreedictionary.com/Benedict's%20reagent
