(iv) The constituents of a true solution cannot be separated by filtration.


(i) A colloid is a homogeneous-looking, but heterogeneous-mixture.

(ii) In a colloid, the particles can be seen only with a powerful microscope.

(iii) In a colloid, the size of particle is between 10-7  10-9 m.

(iv) The constituents of a colloid cannot be separated by filtration.


(i) A suspension is a heterogeneous mixture of a solid dispersed in a liquid, or gas.
