AP Chemistry · Unit 3: Properties of Substances and Mixtures
3.7 Solutions and Mixtures
In short
You must understand that solutions (homogeneous mixtures) can exist as solids, liquids, or gases, and that their macroscopic properties do not vary throughout the sample (unlike heterogeneous mixtures where properties depend on location). The topic focuses on expressing solution composition; while various methods exist, molarity is the expected and most common method used in the laboratory.

How is Solutions and Mixtures tested on the exam?
You will be assessed on your ability to calculate, estimate, or predict unknown quantities (such as solute particles, volume, or molarity) from known quantities. This requires selecting a logical computational pathway, performing dimensional analysis, and strictly attending to precision and significant figures (Mathematical Routine 5.F).
