1.	Explain how the following mixtures may be separated: (i) A mixture of two miscible liquids. (ii) A mixture of benzoic acid and sodium chloride (solid mixture) (iii) A mixture of plant pigments. (iv) Ether and water. (v) Benzic acid-water mixture. (vi) A mixture of benzoic acid and camphor, (vii) A mixture of iodine (I_(2)) and KCI. (viii) A mixture of toulene and phenol. (ix) A mixture of toulene and aniline. (x) A mixture of ethanol and ethanol.
Answer» Answer :(i) By fractional distillation; (ii) By SUBLIMATION; (iii) By chromatography; (iv) By simple distillation; (v) By DISTILLING of water; (vi) Either (i) by using column chromatography or (ii) the MIXTURE is dissolved in `NaHCO_(3)` solution when benzoic acid dissolves (gives effervescence) leaving behind camphor. The filtrate is cooled and then acidified with dil. HCI to get benzoic acid; (vii) Either by sublimation or by extraction with `C CI_(4)` followed by evaporation; (viii) The mixture is dissolved in dilute `NaOH` when phenol dissolves leaving toluene behind. The sodium salt of phenol is then acidified with dil. HCI; (ix) The mixture is extracted with dil. HCI when aniline passes into the aqueous LAYER in the form of hydrochloride salt and recovered by neutralisation with alkali solution; (x) By using `NaHSO_(3)` solution.
