A mixture of sulphur and carbon disulphide is

(a) heterogeneous and shows Tyndall effect
(b) homogeneous and shows Tyndall effect
(c) heterogeneous and does not show Tyndall effect
(d) homogeneous and does not show Tyndall effect.

 Answer: D

Solution: Solution will be homogeneous at molecular level it means if you take any part of the solution percentage of substances will be same. The Tyndall effect is shown by mixture, where mixture has tendency to scatter the light of shorter wavelength and transmit the light of larger wavelength. The Tyndall effect is shown by heterogeneous mixture such as colloid. Sulphur is soluble in carbon disulphide. A solution is formed when sulphur is mixed with carbon disulphide. Therefore, it does not show Tyndall effect. Hence, the correct option is D.
