Question

Explain the following terms giving one example for each.
(i) Miscelles (ii) Aerosol

Answer 1

I) Micelles are aggregates which exhibit colloidal behavior at higher concentration, with the hydrophilic part outside and the hydrophobic part towards the oil and durt particle. Micelles formation is done by substances (soaps and detergents) when dissolved in water.

II) Aerosol is a colloid of fine solid particles or liquid droplets, in air or another gas. Aerosols can be natural or artificial. Examples of natural aerosols are fog, forest exudates and geyser steam. Examples of artificial aerosols are haze, dust, particulate air pollutants and smoke.
