# Given equal concentrations of sodium chloride and sugar in water, how would the osmotic pressure of the sugar solution compare to that of the salt solution....?

Sodium chloride speciates in aqueous solution to give $N {a}^{+}$ and $C {l}^{-}$ ions aquated by water molecules. Because there are 2 particles delivered by each sodium chloride formula unit, it has twice the osmotic potential of a non-electrolytic species such as sugar.
