Answer
Fractional crystallization can be used to separate potassium nitrate from a mixture of potassium nitrate & potassium chlorate.
Process — Add the mixture of potassium nitrate & potassium chlorate to a beaker of water & heat to obtain, hot saturated soln. Cool the hot saturated soln. when crystals of less soluble 'potassium chlorate' crystallize out.
Less soluble [potassium chlorate] is filtered out from the hot saturated soln. recrystallized from hot water and dried.
More soluble [potassium nitrate] is obtained from the filtrate by heating the filtrate followed by cooling. The crystals of the more soluble solid crystallize out.
