ok, this is not exactly a difficult one… just put the same amount of each liquid in a container and into the freezer, and check which one freezes fastest! as for why, I’ll do a little research and get back to you

here we go…

“Freezing-point depression describes the phenomenon that the freezing point of a liquid (a solvent) is depressed when another compound is added, meaning that a solution has a lower freezing point than a pure solvent. This happens whenever a solute is added to a pure solvent, such as water”

http://en.wikipedia.org/wiki/Freezing-point_depression

so pure water would freeze fastest (remember that tap water isnt actually pure water, but I guess it is close enough)
