Question

Preparation methods of colloidal solutions
pls give relevant answer​

Answer 1

Colloidal solution can be prepared by chemical reaction leading to formation of molecules by double decomposition, oxidation, reduction or hydrolysis. These molecules then aggregate leading to form sols. Here Dispersion well working as a condensation. Gold and silver metals are produced from colloidal solution.

there are two principal ways of preparation of colloids: Dispersion of large particles or droplets to the colloidal dimensions by milling, spraying, or application of shear (e.g. shaking, mixing, or high shear mixing).
