


3 Chemical Indicators in this Lab:





Benedicts Solution: Changes color when it comes in contact with a
Monosaccharide like Glucose
Iodine: Changes color when it comes in contact with a Polysaccharide like
Starch
Buiret Solution: Changes color when it comes in contact with a Protein
In Part I, we test KNOWN substances (glucose, starch, oil, gelatin)
Negative Control = Water


Chemicals that indicate the presence of a certain substance by changing
color when they are in contact with that substance.
A CHANGE in color = Positive Result (the substance is there)
NO change in color = Negative Result (the substance is NOT there)
The variable that is the same for all test trials. It is guaranteed to give a
Negative Result
Part II: Test Happy Meal for glucose, starch, lipids, protein
