Question

what is lyophobic colloid? ​

Answer 1

$\huge{\red{\fbox{↪ answer :}}}$

Solution in which the dispersed phase has very little affinity for the dispersion medium. The solution of this colloid is known as lyophobic sol and cannot be directly prepared. They are prepared by special methods. The lyophobic sols are irreversible in nature.

$\huge \mathfrak \orange{❥Answer}$

★ The colloidal system, the dispersed phase does not have an affinity for the dispersion medium so the colloid is not readily formed. They are also known as irreversible sols as they cannot be reconstituted by simply adding dispersion medium after precipitation. They are unstable and can coagulate easily on adding electrolyte, shaking or heating. Lyophobic colloids can be prepared by special methods and require a stabilising agent. Examples of lyophobic colloids are metals and their insoluble compounds , sulphides etc..
