Which of the following properties is responsible for the development of colour to the colloids?
- Correct answerATyndall effect
- BBrownian motion
- CElectrophoresis
- DElectroosmosis
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
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
Hence, the correct answer is option: 'A'.
