GENERAL KNOWLEDGE

Detailed explanation-1: -A colloid is a heterogeneous mixture in which the dispersed particles are intermediate in size between those of a solution and a suspension. The particles are spread evenly throughout the dispersion medium, which can be a solid, liquid, or gas.

Detailed explanation-2: -All homogeneous mixtures are solutions, but heterogenous mixtures can be split into two separate categories: suspensions and colloids.

Detailed explanation-3: -A Colloid is an intermediate between solution and suspension. It has particles with sizes between 2 and 1000 nanometers. A colloid is easily visible to the naked eye.

Detailed explanation-4: -Colloidal solution-Milk, Blood, Soap solution, starch solution, ink. Suspension-Milk of magnesia, chalk powder and water solution, flour in water, muddy water.

Detailed explanation-5: -A suspension is a heterogeneous mixture of particles of one substance distributed throughout a second phase; the dispersed particles separate from the dispersing phase on standing. In contrast, the particles in a colloid are smaller and do not separate on standing.
