colloid solution and colloidal solution
Answers
Hiiii:)
Colloidal solutions, or colloidal suspensions, are nothing but a mixture in which the substances are regularly suspended in a fluid. A colloid is a very tiny and small material that is spread out uniformly all through another substance. ... However, a colloidal solution usually refers to a liquid concoction.

Answer:
(1) The colour of a colloidal solution arises due to scattering of light.
(2) The colour depends upon the wavelengthnof light scattered by dispersed or (colloidal)nparticles
(3) The colour depends on size of colloidal particles. For example gold sol changes colour from red to purple as size of it increases.
(4) The colour of colloidal sol depends on the manner in which the observer receives the scattered light. For example, a mixture of a few drops of milk and large amount of water appears blue when scattered light is observed while it appears red when transmitted light is observed.
