Magnetic Attraction Magnet can be used to separate magnetic solids from non magnetic solids
Sieving Sieve can be used to separate solids with different particle size
Using Suitable Solvents Ability of solute to dissolve in solvent → known as solubility solute is said to be very soluble is more of it can be dissolved in a solvent at a particular temperature
Solids usually have diff. Solubility’s in different solvents. By using suitable solvent, we can separate solids of different solubility’s.
Suitable solvents can be used to separate solid-solid mixtures, in which only one of the solids is soluble in the solvent.
Sublimation Sublimation can be used to separate a substance that changes from solid to gaseous state directly. iodine and naphthalene used in mothballs under sublimation, as well as dry ice ofcourse
Sublimation - can be used to separate a mixture of solids where one sublimes on heating while the others are stable at the sublimation temperature. Solid sublimes into gas and moves away from the mixture. By providing a cool surface for gas to deposit on, gas will change state back into a solid. Resulting solid deposit - known as sublimate Pure sublimates can be easily collected by scraping them off the cool surface.
