What is fractional precipitation?

Answer 1

It is a process for separation of components from a mixture (usually liquid) based on their densities. The substance is heated in closed chamber until complete vapourization. The vapours are then distilled and collected based on their densities into separate fractions.

Answer 2

Fractional precipitation is a technique used to separate and purify different components of a solution based on the differences in their solubilities. By adding a precipitating agent gradually to a solution, one component is selectively precipitated out while the other components remain in solution. This method allows for the separation and isolation of specific substances from a mixture.
