What are some examples of homogeneous mixture heterogeneous mixtures and colliod?

Answer 1

Homogeneous - Any mixture that looks consistent throughout - eg. - Steel and most other metallic alloys, glass (un)saturated salt solution in H2O. You can remember this easily if you imagine a homosexual relation ship. 2 people of the same gender, they are the same as one another.

Heterogeneous - Any mixture that has obvious components that don't become of the same consistency. Eg - Granite rock, concrete, peanut brittle. Heterosexual couple - 2 "unlike" people "mixed" together.

Colloid - A heterogeneous solution that has been "homogenized" or the unlike particles have been made small enough that they don't separate from the solution, or at least temporarily remain suspended in the solution. Milk is a good example. Lipids are made small enough to remain suspended in the mixture, otherwise you'd have butter in the top of your milk jug. :)
