Question

Give any two examples of coloidal solution

Answer 1

A colloidal substance is any which has the quality of having another substance diffused evenly throughout it.

In the example of milk, there is a dispersal of liquid butterfat within a water-based solution. In this case, the liquid butterfat, the smaller molecule, is within the range of 1 nanometer and 1 micrometer, making it invisible to an optical microscope. When the mixture becomes homogenous, that is to say that no part of the solution has a greater or lesser concentration of the dispersed phase than any other, it can be said that the solution is colloidal in nature. The larger solution that contains the dispersed phase is called the continuous phase, or the dispersion medium, since its size and distribution does not change, while the dispersed phase spreads throughout it.
