The number of colloidal systems from the following, which will have 'liquid' as the dispersion medium, is _____. Gem stones, paints, smoke, cheese, milk, hair cream, insecticide sprays, froth, soap lather

Correct answer

0

Step-by-step solution

The phase that is scattered or present in the form of colloidal particles is called dispersed phase and the medium in which the colloidal particles are dispersed is called the dispersion medium. Coloured gemstones are solid sols, colloids in which solid particles are dispersed in solid medium. In paints, small amount of solid pigments are dispersed in a large amount of liquid solvent. So, it is an example of a solid in liquid mixture. Smoke is a solid aerosol-type colloid consisting of the solid dispersed phase in
