A mixture of common salt and water can be separated completely by the process of distillation. The distillation can be used to separate a liquid from dissolved non-volatile solids. The salt water mixture is taken in the distillation flask $A$ and heated. Some porcelain pieces are put in the distillation flask to avoid bumping of the solution due to uneven heating. On heating, water forms vapours which rise up and come out through the side tube $B$ of the distillation flask, and go into water condenser $C.$ Cold water from tap is circulated through the outer tube of condenser for cooling the vapours. The hot vapours get cooled in the condenser to form pure water (i.e. distilled water) which trickles down from the condenser and collects in the beaker $D.$ Since the salt is non-volatile, so it remains behind in the distillation flask.

- 8$A , B$ and $C$ are all liquids. Liquid $A$ has a comparatively low boiling point. On heating, liquid a vaporizes completely without leaving behind any residue. Liquid $A$ is being used increasingly as a fuel in motor vehicles either alone or by mixing with petrol. Liquid $B$ has a very high boiling point. It also vaporizes completely on heating, without leaving any residue. Liquid $B$ is a conductor of electricity and used in making thermometers. Liquid $c$ has a moderate boiling point. On heating, liquid $C$ vaporises leaving behind a white solid $D$ which is used in cooking vegetables. The condensation of vapours from $C$ give a liquid $E$ which turns anhydrous $CuSO _4$ to blue.View Solution

e. What do you think is liquid $E$ ? - 9Iron powder and sulphur powder were mixed together and divided into two parts $A$ and $B.$ When part $A$ was heated strongly over a burner, then a substance $C$ was formed. The part $B$ was, however, not heated at all. When dilute hydrochloric acid was added to substance $C,$ then gas $D$ was evolved and when dilute hydrochloric acid was added to part $B$ then gas $E$ was evolved.View Solution
