Separation of Substances

Separation of two substances by fractional crystallisation depends upon their difference in

Separation of two substances by fractional crystallisation depends upon their differences in:

A certain mass of substance in 10 g of benzene lowers the freezing point by 1.28^(@)C and in 100 g of water lowers the freezing point by 1.395^(@)C separately. If the substance has normal molecular weight in benzene and completely dissociated in water, calculate number of moles of ions formed by its 1 mole dissociation in water (K_(f_("water"))=1.86, K_(f_("benzene"))=5.00)

Latest technique for purification isolation and separation of organis substance is

The particles of a substance suspended in a suspension can be separated by
