A mixture of sulphur and carbon disulphide is

A

heterogeneous and shows Tyndall efferct

B

homogeneous and shows Tyndall effect

C

heterogeneous and does not show Tyndall effect

D

homogeneous and does not show Tyndall effect

Text Solution

Verified by Experts

The correct Answer is:
A
A mixture of sulphur a and carbon disulphide is a heterogeneous colloid and shows Tyndall effect. In a colloidal solution, the particles are big enough to scatter light.
The scattering of light by colloidal particles is known as Tyndall effect. Colloids are actually heterogeneous in nature though they appear to be homogeneous.
