Question
Which of the following mixture is not an example of a colloidal solution?
Hint:
D
The correct answer is:
- Blood is a type of colloid. The dispersed phase consists of blood cells, nutrients, minerals, and so forth, and the dispersing medium is plasma (containing water and other dissolved components).
- Because the dispersed particles are indefinitely scattered throughout the binder, dried paint is often termed a colloid (dispersing medium). When paint is made, the pigments are very finely ground, frequently together with the binder, to achieve colloidal particle size.
- Fat and chocolate particles are suspended in a fluid; they do not dissolve in water but are small enough to spread evenly and appear uniform so they act as a solution.
- Makeup is a colloid as they reflect light showing Tyndall effect.
