Based on the type of dispersed phase, what type of colloids are micelles?

Based on the type of dispersed phase micelles are associated with colloids.


Explanation:


Some substances when at a high concentration show colloidal behaviour. They form aggregates called micelles. These aggregated particles have two parts- hydrophilic(water-attracting) and hydrophobic(water-repelling) parts. These charged particles aggregate with particles and form large-aggregates called micelles in a solution. Therefore a micelle can be called as an associated colloid.


A typical structure of micelle:




The charged particles get arranged in this way and thus form a micelle.
