    Melting point decrease and boiling point increase on addition of a solute.

    Sure... imagine that in a beaker you have water and in it you put some salt what happens is that the salt sorts of gets into the spaces between the water molecules. So if we look at the surface of water we find that water molecules from the bulk of the liquid arent really able to come to the surface due to the salt molecules. When we say that something has started to boil we mean that the vapour pressure of that soln is equal to the atmospheric pressure. So we need to provide more height for enough vapour pressure to build up. Now reason it out for decrease in meting point (I hope I havent confused you even more)

    the addition of salt to a solvent ,such as water, lowers the amount of the solvent present at the surface. the more solvent at the surface the easier it vaporizes, when there is a solute present(salt) more temperature is needed to vaporize the solvent. Essentially the salt crystals stop the water from boiling
