Solution

Column I Column II
(i) Two solids which
have different
solubility's in a
solvent and which
do not undergo
reaction when
dissolved in it. On dissolving in solvent, the solid which is insoluble is separated out
by filtration and the soluble solid is separated by crystallization.
(ii) Liquid that
decomposes at its
boiling point Distillation under reduced pressure is done, because at low pressure
vapours are formed below its boiling point and decomposition does not take place.
(iii) Steam volatlie
liquid Liquid is converted into vapours by passing steam followed by
condensation.
(iv) Two liquids
which have boiling
points close to each other The vapours of such liquids are formed within the same
temperature range and are condensed simultaneously. The
technique of fractional distillation is used in such cases. In this
technique, vapours of a liquid mixture are passed through a
fractionating column before condensation. The fractionating column
is fitted over the mouth of the round bottom flask.
(v) Two liquids with
large difference in
boiling points. Liquids having different boiling points vaporize at different
temperatures. The vapours are cooled and the liquids so formed are
collected separately.
