associated colloids
Answers
Associated colloids are those who behaves normally at lower concenterations but shows the properties of colloid due to aggregated particles.
Answer:
(i) Many substances like sodium salt of long size fatty acids behave as electrolytes in aqueous solution.
(ii) As their concentration increases they get associate forming a colloidal solution.
(iii) The associated particles are called micelles For example, soap, detergents Soap has a long hydrophobic hydrocarbon chain, called tail, attached to hydrophilic ionic group carboxylate, called head. In water the soap molecules arrange themselves to form spherical particles that are called micelles In each micelle, the hydrophobic tails of soap molecules point to the centre and the hydrophilic heads lie on the surface of the sphere. As a result of this, soap dispersion in water is stable.
