Methods for Separation

A. Separation of Husk from Wheat
The method used for separating husk from wheat is called winnowing. In this method, the mixture of husk and wheat is thrown from a height. The wind blows away the lighter husk, and the heavier wheat falls to the ground.

B. Separation of Sand from Water
The method used for separating sand from water is called filtration. In this method, the mixture is poured through a filter paper. The sand particles get trapped in the filter paper, and the water passes through it.

C. Separation of Stones from Daal
The method used for separating stones from daal is called handpicking. In this method, the mixture is spread on a flat surface, and the stones are removed by hand.

D. Separation of Camphor Powder and Common Salt Powder
The method used for separating camphor powder and common salt powder is called sublimation. In this method, the mixture is heated, and camphor powder sublimes (changes directly from a solid to a gas) leaving behind common salt powder.

E. Separation of Butter from Milk
The method used for separating butter from milk is called centrifugation. In this method, the mixture is spun in a centrifuge. The heavier butter separates from the lighter milk and collects at the bottom.

F. Separation of Pure Potash Alum from Impure Potash Alum Phitkari
The method used for separating pure potash alum from impure potash alum phitkari is called crystallization. In this method, the mixture is dissolved in water, and the solution is heated to dissolve the impurities. The solution is then cooled slowly, and pure potash alum crystals are formed.

In conclusion, there are various methods used for separation, and the choice of the method depends on the nature of the mixture to be separated. These methods, when done correctly, enable us to obtain pure substances from mixtures.
