B) most colloids appear cloudy or opaque unless very dilute
C) colloids can only be liquids
D) colloids do not scatter light
Explanation / Answer
Answer : B) most colloids appear cloudy or opaque unless very dilute
In colloids the particle size of the dispersed phase ranges from 1 nanometer to 1 micrometer. So statement A is false
The dispersion medium of a colloid can be solid or a gas also.Therefore the statement C is false
Colloids do scatter light.This phenomenon is known as Tyndall effect.Hence the statement D is false
