What are micelles? Give an example.

1.	What are micelles? Give an example.
Answer» Micelles are associated colloids which behave as normal strong electrolytes at low concentration but behave as colloidal particles at higher concentrations. For example:- soap molecules when dissolved in water gives sodium and stearate ions. The stearate ions associate to form ionic micelles of colloidal size. C₁₇H₃₅COONa ↔ C₁₇H₃₅COO^- + Na⁺
