One of the most important properties of solutions is evaporation,
is that its vapor pressure lowers (or the number of solvent molecules in gaseous
form decreases) as more solute(salt)is added. In addition to the lower vapor pressure
at the start, as the solvent evaporates, this effect becomes more and more pronounced since
there will be more solute (the salt) in the remaining solution (because of the reduced
amount or volume of solvent (the water). Thus, one would expect that the
solvent only sample should always evaporate to dryness first.
