Those mixtures in which the substances are completely mixed together and are indistinguishable from one another, are called homogeneous mixtures. They have a uniform composition throughout its mass. All the homogeneous mixtures are called solutions. Examples: Sugar solution, salt solution, copper sulphate solution, etc. Those mixtures in which the substances remain separate and one substance is spread throughout the other substance as small particles, droplets or bubbles, are called heterogeneous mixtures. Heterogeneous mixture does not have a uniform composition throughout its mass. Example: Starch solution, soap solution.

- 5$A , B$ 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

- 9There 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
