Editing Colligative properties (section)

==History==
The word colligative (Latin: co, ligare) was introduced in 1891 by [[Wilhelm Ostwald]]. Ostwald classified solute properties in three categories:<ref>W.B. Jensen, J. Chem. Educ. 75, 679 (1998) ''Logic, History, and the Chemistry Textbook  I. Does Chemistry Have a Logical Structure?''</ref><ref>[[Homer W. Smith|H.W. Smith]], Circulation 21, 808 (1960) ''Theory of Solutions: A Knowledge of the Laws of Solutions ...''</ref> 
# ''colligative'' properties, which depend only on solute concentration and temperature and are independent of the nature of the solute particles
# ''additive'' properties such as mass, which are the sums of properties of the constituent particles and therefore depend also on the composition (or molecular formula) of the solute, and 
# ''constitutional'' properties, which depend further on the molecular structure of the given solute.
