is used in collecting a pure liquid from mixture of liquids through the processes of evaporation and condensation
A
liquid-liquid extraction
B
distillation
C
chromatography
D
centrifugation
Explanation: 

Detailed explanation-1: -Distillation refers to the selective boiling and subsequent condensation of a component in a liquid mixture. It is a separation technique that can be used to either increase the concentration of a particular component in the mixture or to obtain (almost) pure components from the mixture.

Detailed explanation-2: -Distillation is a powerful technique for separating the component substance from a miscible fluid mixture by means of selective evaporation and condensation.

Detailed explanation-3: -Distillation is the method of getting a pure liquid from a solution by evaporating and then condensing the vapours. When any solution is heated, the liquid component of the mixture evaporates in order to form vapours. These vapours are then condensed back to liquid form. The liquid obtained in this case is very pure.

Detailed explanation-4: -Distillation is the process of vaporizing a liquid and recovering it by condensing the vapors. The liquid formed by this condensation is called the distillate.

Detailed explanation-5: -Distillation involves two processes i.e. evaporation followed by condensation. Distillation is the process of heating water to form water vapours and then cooling the hot water vapour to get water.
