Hi!
How do we know if we have a homogeneous or heterogeneous mixture? Also, in which of these 2 categories does a colloid fit?
Thanks already!

Thank you for your question 😊
A heterogeneous mixture consists of substances which are visibly distinguishable. A fruit salad or a raisin bread are examples of heterogeneous mixtures, because it is possible to distinguish the different elements that compose them.
In a homogeneous mixture, the components cannot be distinguished; there seems to be only one phase. This mixture includes alloys, solutions and colloids. Blood, vinegar and brass are examples of homogeneous mixtures.
Colloids therefore belong to the family of heterogeneous mixtures, since, when we observe one using a microscope, we can then distinguish different phases.
Don't hesitate to come back if you have other questions!
