Question

explain Tyndall effect in homogeneous and heterogeneous mixtures

Answer 1

The scattering of light by colloidal particles is known as Tyndall effect.

Tyndall effect can be observed in Heterogeneous mixtures like :

*   Suspension - in stable form

*   Colloidal solutions

In colloidal solutions particles are big enough to scatter light.

If a beam of light is put in collodial solution, kept in a dark room, the path of the light beam is illuminated and becomes visible when seen from the other side.

This scattered light enters our eyes and we are able to see the path of the light.

Answer 2

TYNDALL EFFECT IS THE PROCESS OF SCATTERING OF LIGHT IN COLLOIDAL SOLUTION.

HOMOGENOUS MIXTURE

THERE WONT BE TYNDALL EFFECT AS THE MIXTURE IS COMPLETELY DISSOLVED IN THE SOLUTION. SO THE PASSAGE OF LIGHT IS NOT VISSIBLE.

HETEROGENOUS MIXTURE

THERE WILL BE TYNDALL EFFECT DUE TO THE PRESENCE OF INSOLUBE SUBSTANCES IN THE MIXTURE. SO PASSAGE OF LIGHT WILL BE VISIBLE
