quote:Originally posted by rosyUr, the change in boiling and freezing point observed should be as Micky says but it's not actually to do with the density... it's thermodynamics (what isn't!)The reason more salt dissolves in water than sugar isn't down to the particle size its to do with the different interactions between the particles, with each other in the solid and with the water molecules and between the water molecules.
quote:Originally posted by rosyThe boiling point is expected by theory to increase, because the disorder (entropy) of the solution is increased by the presence of solutes and so the dilute solution is favoured over the more concentrated solution and the gas at a slightly higher temperature than the pure solvent.
