Question

Colour of colloidal solution depends on:

• A. Size and nature of colloidal particles
• B. formation of complex
• C. formation of hydrated crystal
• D. None of the above

Answer 1

The correct option is A Size and nature of colloidal particles

Colour is a physical property of colloidal solution.​ Colloidal solutions are generally coloured.
The colour of the colloidal solution depends on​ wavelength of light​ scattered by dispersed particles.
Wavelength of light​ scattered by dispersed particles depends on size and nature of particles.
Thus, option (a) is correct.​
