How would the result be affected If a student places a sugar cube into one of the unknown solutions in the experiment?
From my previous lab, i'm assuming it's the same, there are 4
tests: monosaccharaide, starch, lipid, and protein.
If a sugar cube is to be placed into the unknown solution and
then tested by the 4 tests, there would be NO affect:
* Note: Some will think that placing a sugar cube into the
solution will change the results of the monosaccharaide test, but
there won't be. Remember, the monosaccharide only tests positive in
the presence of a monosaccharaide, but sucrose is a DISACCHARIDE,
so there will be no affect.
As for the other tests, they are indicators of starch, lipids,
and proteins, again, nothing else. Therefore, sugar has no affect
on the results whatsoever.
