Question

What is a colloidal solution​

Answer 1

Answer:

In chemistry, a colloid is a phase separated mixture in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance.

Answer 2

The ions aggregate to form small particles that remain suspended in the liquid. A stable hydrophobic colloid can be made to coagulate by introducing ions into the dispersing medium. For example, the milk which contains a colloidal suspension of protein-rich casein micelles with a hydrophobic core.
