Use a melting point apparatus. That is basically an electric heater with a thermometer on it into which you put little tubes containing your samples. You might want to insulate it a bit and put it in a cold chamber of some sort. Cool it down to about 0C, insert your acetic acid in the little tube, and then warm it slowly. Observe the melting somewhere between 10 and 20C, depending on the purity of your acetic acid.

Acetic acid, also known as ethanoic acid, is an organic chemical compound best recognized for giving vinegar its sour taste and pungent smell. Pure water-free acetic acid (glacial acetic acid) is a colorless hygroscopic liquid and freezes below 16.7°C (62°F) to a colourless crystalline solid. Acetic acid is corrosive, and its vapour is irritating to eyes and nose, although it is a weak acid based on its ability to dissociate in aqueous solutions.
