...paper, leaving the residue on the impermeable substance/filtrating medium and the filtrate to pass through. | Dissolved solids in liquids Evaporation | If the liquid in the mixture is more volatile (boiling point is lower) than the soluble solid, the soluble solid will remain while the liquid evaporates. The procedure employs the use of an evaporating dish and a Bunsen burner. | Crystallisation | Another method of dissolved solids from a liquid mixture (solution)The impure salt is dissolved in water at a high temperature to create a concentrated solution.The mixture is then cooled and the salt crystallises, leaving the impurity in the solution.This crystallised slat contains much less of the impurity than before. The salt can then be filtered and dried.Sugar cane industry. | Assess separation techniques for their suitability in separating examples of earth materials, identifying the differences in properties which enable these separations Yes, fractional distillation can separate a mixture of oxygen and nitrogen because they have similar (but not the same) boiling points. Could filtration successfully separate sand from a sand-salt mixture? No. Without water the salts in the sand and salt mixture will not separate out via filtration because filtration requires an insoluble solid plus a liquid mixture, which in this case would be salt + water Describe situations in which gravimetric analysis supplies useful data for chemists and other scientists * the process...
