The correct answer is Colloids are homogeneous mixtures.Concept:Colloidal solution/ colloid:The type of solution in which the size of the solute particle is in the range of 1 to 100 nm, is called a colloid.A colloid is a heterogeneous system in which one substance is dispersed (dispersed phase or colloidal particles) in another substance which is called a dispersion medium.Explanation:Properties of colloids:A colloid appears to be homogeneous but actually, it is heterogeneous.The particles of most of the colloids cannot be seen even with a microscope.It scatters a beam of light passing through it (Tyndall effect).The size of the solute particle is in the range of 1 to 100 nm.Since they are heterogeneous in nature, centrifugation techniques can be used to separate the particles.Additional InformationStatement True/ falseColloidal particles can be separated from a mixture of centrifugation.TrueColloids show the Tyndall effect.TrueColloidal particles cannot be seen with naked eyesTrueColloids are homogeneous mixtures.False
