What are micelles ? Give one example.

Text Solution

Verified by Experts

Micelles : Some substances which at low concentrations behave as normal strong electrolytes, but at high concentrations exhibit colloidal behaviour due to formation of aggregates. The aggregated particles thus formed are called micelles.
Eg : Stearate ions `(C_(17)H_(33)COO^(-))` associate together in high concentration , in a solution of soap in water and forms a micelle.
