Question

A mixture of sulfur and carbon disulfide is a heterogeneous and shows the Tyndall effect b homogeneous and shows the Tyndall effect c heterogeneous and does not show Tyndall effect d homogeneous and does not show Tyndall effect

Accepted Answer

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

The answer is a) heterogeneous and shows the Tyndall effect.

Explanation:

A mixture of sulphur and carbon disulphide is heterogeneous and shows Tyndall effect because in a colloidal solution the particles are big enough to scatter light.
