KPK 11th Class Chemistry Chapter 10 Solutions and Colloids Short Questions Answers

Classify colloids on the basis of their behavior towards medium and the physical states of matter.

Classification on the basis of components:
On the basis of components there are eight types of colloidal suspension as given in the table. Types of colloidal suspension

S.No	Dispersed phase	Dispersion medium	Special name	Typical example
1.	Gas	Gas		Cannot exit, both components diffuse into each other to form a homogeneous
2.	Liquid	Foam,		Soap Lather, been, foam, whipped cream
3.	Liquid	Gas	Fog, aerosol	Clouds, fog, moist. Aerosol sprays
4.		Liquid	emulsion	Homogenized milk, H2O in oil or benzene
5.		Solid	gel	Halwa, gellies, ointments, sili ca gel Fe (OH)2
6.	Solis	Gas	Smoke	Coal smoke(carbon dispersed)vNH4Cl fumes, lodine vapours in air suspended dust
7.		Liquid	Sol or colloidal solution	As2S3, Gold or Fe (OH)3 sol solution of high polymer, milk lassi

8.

Solid

Colloidal gases, minerals, gems, alloys and mixed crystals.

1. Behavior towards liquids:

Depending upon the force of attraction or repulsion between the dispersed particles and dispersion medium, a colloidal suspension may be lyophillic and lyophobic.
If a force of attraction exists between the particles of dispersed phase and dispersion medium, the sol is called lyophillic. If the dispersion medium is water, then sol is termed as hydrophilic.

Explain and differentiate between the different concentration units.

The amount of a solute dissolved in a given quantity of solvent or solution is called concentration. There are many ways of expressing the concentration of a solution i.e. molarity, molatily, formality, normality, mole fraction, percentage composition etc.
The percentage composition of a solution is expressed in four ways.
