This class was spent doing a lab on polar and non- polar solvents.
The purpose of this lab was to fnd out if glycerin is polar or non- polar.
The procedure was as followed:
-get 6 test tubes and divide them into 3 groups.
-one test tube from each group was filled with water while the other was filled with paint thinner.
-the first group had salt dissolved in it, the second group had sugar, and the third had iodine crystals.
-each tube had a stopper and was shaken to mix the solute and solvent.
-then we recorded our observations.
