A solvent is polar if it has a dipole moment greater than 1.6 D and a dielectric constant greater than 5. The values for acetone are µ = 2.88 D and ε = 21. So acetone is a polar solvent. A protic solvent has an H atom bound to O or N. It can use its H atom to participate in H-bonding.
The drying agents commonly used in the organic laboratories are the anhydrous forms of calcium chloride (CaCl 2), sodium sulfate (Na 2 SO 4) Calcium sulfate (CaSO 4 (as Drierite) and magnesium sulfate (MgSO 4).

Heat test Anhydrous: When heating the sample slowly, it first fuses gradually and boils, and later decomposes evolving an unpleasant odour of acetone. A solution of the residue gives alkaline reaction with litmus paper. Trihydrate: When heating the sample slowly, it liquefies. Then water evaporates, and a powder forms.
