KPK 11th Class Chemistry Chapter 10 Solutions and Colloids Short Questions Answers
Solution: 1. Homogeneous mixture of two or more than two substances whose composition can be changed within certain limits. Example: sugar in water, NaCl in water Suspension: Lather, been, foam, whipped cream Depending upon the force of attraction or repulsion between the dispersed particles and dispersion medium, a colloidal suspension may be lyophillic and lyophobic.How a given mixture can be differentiated into a true solution or coarse suspension.
Classify colloids on the basis of their behavior towards medium and the physical states of matter.
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

8.
Solid
Colloidal gases, minerals, gems, alloys and mixed crystals.
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 percentage composition of a solution is expressed in four ways.
How to Write Perfect Short Answers?
In Board Exams, the examiner looks for specific keywords and presentation. Here is how to attempt Chapter 10 questions:
- Ideal Length: Write 3 to 5 lines for each short question. Too short gets fewer marks, too long wastes time.
- Highlighting: Use a Blue Marker to highlight key dates, names, or scientific terms in your answer.
- Units & Formulas: Always write the formula and SI unit. Without units, 0.5 marks are deducted.
