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: -Aerosols: Solid or liquid mixed with gas; Example: fog (liquid in gas) Sols: Solid mixed with liquid; Example: Paint. Emulsion: Liquid with liquid; Example: oil and water.

Detailed explanation-3: -A mixture of two different components, where the solid forms a dispersed phase and the liquid forms a dispersion medium, the solution is called colloidal solution or sol. Basically, solid+liquid is a colloidal solution or sol.

Detailed explanation-4: -True solution-Salt solution, copper sulphate solution, sugar and water solution, vinegar, air, brass. 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: -Sol is a colloidal suspension with solid particles in a liquid. Emulsion is between two liquids. Foam is formed when many gas particles are trapped in a liquid or solid. Aerosol contains small particles of liquid or solid dispersed in a gas. 29-Jan-2023
