Question

Give an example of each of the following types of solutions:

(a) a gas in a liquid

(b) a gas in a gas

(c) a solid in a solid

Short answer

1. \({{\rm{O}}_{\rm{2}}}\)in water;
2. \({{\rm{O}}_{\rm{2}}}\)in \({{\rm{N}}_{\rm{2}}}\) (air);
3. Bronze (solution of tin or other metals in copper).

Step-by-step solution

Solution

Solutions may be colored or when the particle does not settle down on standing, these solutions are termed as colloids. And their properties lie between solutions and suspensions.

The component which is present in a less amount is known as dispersed phase.

The component which is present in a major amount is known as dispersion medium.

(a) Gas in a liquid

In this solution, gas act as the dispersed phase and liquid act as the dispersion medium. This type of solution generally termed as Foam.

Example: Oxygen in water

(b) Gas in a gas

The solution in which dispersed phase and dispersion medium both are gas.

For example, \({{\rm{O}}_{\rm{2}}}\) in \({{\rm{N}}_{\rm{2}}}\) (air)

(c) Solid in a solid

In this solution the dispersed phase and dispersed medium both are solid Colored gems and alloys are example of these solid in a solid solution..

For example, Bronze (solution of tin or other metals in copper).
