Options
- A. Tyndall effect
- B. Brownian motion
- C. Electrophoresis
- D. Electroosmosis
Answer
A. Tyndall effect
Step-by-step solution
The colour of a colloidal solution depends on the wavelength of light scattered by the dispersed particles. The scattering of light by colloidal particles is known as the Tyndall effect. Therefore, the Tyndall effect is responsible for the development of colour in colloids. Answer: Tyndall effect
