Which of the following properties is responsible for the development of colour to the colloids?

Options

  1. ATyndall effect
  2. BBrownian motion
  3. CElectrophoresis
  4. DElectroosmosis

Correct 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
