Chapter 11, Problem 10RQ

Interpretation Introduction

Interpretation: The colloidal dispersion and its examples are to be discussed. Explanation of Tyndall effect is to be given and term coagulation has to be explained.

Concept Introduction:

Colloidal dispersion is deferral of small particles in certain medium. The particles are in range of $\text{1-1000}\text{nm}$. They can be classified based on their states of dispersing phase and dispersing medium.

Tyndall effect is the dispersion of particles by light and its often used to differentiate the true solution and suspension.

The devastation of colloid either by heating o by addition of electrolyte is called as coagulation.
