When was freezing point depression discovered?
It’s hard to say when freezing point depression was “officially” discovered. It was first documented by the ancient Greeks of Aristotle’s time (384-322 B.C.) and observed by Joseph Black in the 1760s. It was not understood in a general sense until 1788, when Charles Blagden showed that freezing point depression is directly proportional to the amount of a solute in a solution.Source:Modern Inorganic Chemistry: Blagden’s LawThe Pre-History of Cryoscopy: What Was Done Before Raoult?Bodner Research Web: Colligative PropertiesMore Information:European Journal of Physics: Reproducing Black’s experiments: freezing point depression…
