Question

What is colloid and what is the various property

Answer 1

$\mathfrak{\huge{\orange{\underline{\underline{Answer :}}}}}$

A colloid is a heterogeneous mixture whose particles are not as small as solution but they are so small that cannot be seen by naked eye. When a beam of light is passed through a colloid then the path of the light becomes visible. For example milk, smoke etc.

Answer 2

Answer:

General properties of colloidal systems are as follows:

(1) Colloidal system is heterogeneous and consists of two phases, dispersed phase and dispersion medium.

(2) The dispersed phase particles pass slowly through parchment paper or animal membrane, but readily pass through ordinary filter paper.

(3) The colloidal systems exhibit optical property like Tyndal effect, kinetic property like Brownian motion, electrical properties like electrophoresis a colour.
