Match the mixture in Column-I with the method in Column-II that can be used to separate it.

Correct option is A

The correct answer is (A) – (iii), (B) – (iv), (C) – (i), (D) – (ii).
Sawdust and water: Sawdust is insoluble in water, so it can be separated by filtration. The mixture can be passed through a filter paper, and the sawdust will be retained on the filter paper while the water passes through.
Iodine and sand: Iodine is a solid that can undergo sublimation, which means it can change directly from a solid to a gas without passing through the liquid phase. By heating the mixture, the iodine will sublime, leaving behind the sand.
Salt and water: Salt is soluble in water, so the mixture can be separated by evaporation. By heating the mixture, the water will evaporate, leaving the salt behind.
Cream from curd: Cream can be separated from curd by using centrifugation. Centrifugation involves spinning the mixture at high speed, causing the denser cream to separate from the lighter curd.
