Interpretation Introduction

Interpretation:

The solvents and the suspended particles of the given colloids are to be categorized.

Concept Introduction:

Colloids are non-crystalline homogeneous substances which consist of large particles of a substance that is dispersed throughout another substance. The size of colloidal particles lies between the range of $1\times {10}^3\text{pm to }1\times {10}^6\text{pm}$.

Tyndall effect is the scattering of light by suspended particles of a fluid, when a beam of light is passed through the fluid. This scattering of light can be confirmed by passing a beam of light, with the help of a laser pointer, through the fluid.
