Answer:
Ans.1. A mixture of sand and potash alum is separated by filtration followed by evaporation. The mixture contains two constituents, i.e., potash alum and sand. Mix both the constituents thoroughly with water so that potash alum gets dissolved in water. However, sand, being insoluble in water, will not get dissolved in it.
Ans.2 In factories, scrap iron is separated from the heap of waste materials by using big electromagnets fitted to a crane.
