Which of these is the most preferred separation technique for the isolation of solutes where the purity of the constituent is of utmost importance?
Distillation separates components of a liquid mixture by heating and cooling, which vaporizes and condenses the components based on their boiling points. This technique is often used in industries like pharmaceuticals and fine chemicals. This is better suited for separation mixtures based on differences in boiling points.
Recrystallization separates a dissolved solid from a solution by heating the solution until the solvent evaporates, leaving a saturated solution. This technique is often used to purify solids.
However, recrystallization is generally considered a better method of achieving high purity of solutes because of higher purity of 99.9% while distillation 99%, less contamination, better separation etc.
Nonetheless, the choice between recrystallization and distillation ultimately depends on the specific properties of the solutes. Thus option C is the correct answer
