At first, the mixture of common salt, sulphur powder and sand is shaken with carbon disulphide. Sulphur dissolves in carbon disulphide whereas common salt and sand remain un-dissolved. The solution is then filtered, common salt and sand mixture is obtained as residue. On evaporating the filtrate, carbon disulphide solvent is eliminated and solid sulphur remains behind. Now, the common salt and sand mixture is shaken with water. Common salt gets dissolved in water. The solution is then filtered, sand is obtained as residue. The filtrate is then evaporated to get crystals of common salt.

Similar Questions
- 1There are three substances $X, Y$ and $Z.$ The substance $X$ does not have a fixed melting point or boiling point and it still shows the individual properties of its constituents. The substance $Y$ is a pure substance which occurs in nature as such. The substance $Y$ has a fixed melting point and boiling point but it cannot be broken down into simpler substances by any chemical means. The substance $Z$ is also a pure substance whose properties are entirely different from those of its constituents. The substance $Z$ can, however, be divided by electrolysis into two substances which belong to the same class of substances as $Y.$View Solution

- 2$A , B$ 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

- 7There is a large group of materials $P$ which can be divided into three groups $Q, R,$ and $S$ on the basis of their properties. The substances belonging to group $Q$ can be solids, liquids or gases. The solids belonging to group $Q$ are usually electrical insulators. Most of the substances of group $R$ are solids which are good conductors of electricity. The substances belonging to group $S$ are neither insulators like $Q$ nor good conductors like $R.$ The properties of $S$ are intermediate between those of $Q$ and $R.$View Solution
