Question

The mixture of potassium nitrate and common salt is separated by which method?options are
sublimation
evaporation
fractional crystalisation
centrifugaton

Answer 1

Potassium nitrate and sodium chloride are separated by fractional crystallization

Answer 2

Heat the solution and allow it to cool and filter the precipitate of potassium chloride since it only dissolves in hot water. Heat the remaining filtrate until crystals of sodium chloride start forming and give it time to cool in order to form more crystals.
