(b) ammonium chloride from sand by sublimation as ammonium chloride being sublimable undergoes sublimation.
(c) chalk powder from water by filtration
(d) iron from sulphur by magnetic separation
(e) water and alcohol by fractional distillation
(f) sodium chloride and potassium nitrate by sublimation
(g) after adding water to the solution of calcium carbonate and sodium chloride, sodium chloride dissolve in water leaving behind calcium carbonate.
