Question

Give an example of solid in solid solution and liquid in liquid solution.. Write the name of the dispersed phase and dispersion medium in sol and foam. Define Colloid and Saturated solution.

Answer 1

Answer and Explanation:

$\huge \text{\huge {\underline {SOLUTIONS} }}$

$\blacksquare$ Solutions are homogenous mixture composed of 2 or more substances

$\blacksquare$ Solutions mostly have 2 components :

1. Solvent
2. Solute

$\blacksquare$ Homogenous implies that the concentration of solute is constant throughout the bulk of the solution

$\blacksquare$ Solutions are of different types namely :

1. Solid - solid
2. Solid - liquid
3. Solid - gas
4. Liquid - solid
5. Liquid - liquid
6. Liquid - gas
7. Gas - solid
8. Gas - liquid
9. Gas - gas

$\blacksquare$ Examples of :

1. solid - solid solution $\implies$ alloys
2. liquid - liquid solution $\implies$ alcohol in water

$\blacksquare$ Saturated solutions are solutions into which we cannot add anymore solute at a particular temperature

$\blacksquare$ More solute can be added if we increase the temperature

$\huge \text{\huge {\underline {COLLOIDS} }}$

$\blacksquare$ Colloids or colloidal solutions are a phase separated mixture in which one substance of dispersed insoluble or soluble particles is suspended throughout another substance

$\blacksquare$ Colloids have 2 phases :

1. Dispersed phase
2. Dispersion medium

$\blacksquare$ In sol :

1. Dispersed phase $\implies$ Solid
2. Dispersion medium $\implies$ Liquid

$\blacksquare$ In foam :

1. Dispersed phase $\implies$ Gas
2. Disperse medium $\implies$ Liquid
