Question

1.(a) Mention the types of mechanisms of separation, and discuss in detail (with sketch) (6 m)

Answer 1

crystallization: Separation from a liquid solution into a solid crystalline state based on the solubility.

filtration: It is the process of separating the suspended solids from a liquid solution based on their particle size.

distillation: It is the process of separating components form the liquid mixture by selective boiling and condensation. It is based on the boiling point of components present in the liquid( relative volatility). Different types of distillations are

-fractional distillation - simple distillation -vacuum distillation -steam distillation

extraction : It includes solid liquid and liquid liquid extraction. A solvent is added to the mixture and it will selectively dissolves one or more components of the mixture to proceed the separation process.

absorption : seperation based on the differenec in solubility of components.
