Chapter 2
Mixtures, Solutions and Colloids, Separation of Mixtures, Elements, Compounds and Changes
A shop sells pure milk, pure butter and pure honey. Is the milk that you drink really pure in the way a chemist uses the word? In this chapter we learn what scientists mean by a pure substance, and how it differs from a mixture. We study solutions, suspensions and colloids, and the ways to separate the parts of a mixture. Then we meet the elements and the compounds that everything is made of. Python helps us with the calculations.
