Acids and bases touch upon virtually all areas of chemistry, biochemistry, and physiology. This set of lessons will get you started by presenting the underlying concepts in a systematic way. Aside from the section on pH which presumes an elementary knowledge of logarithms, there is no math here.
If you take the time to master this unit, you are almost guaranteed to pass Chemistry!
How to predict the direction of an acid-base reaction. Spend some time here, and your reward will be a far better understanding of acid-base chemistry.
Most elementary courses will cover only the first two topics of this section.
It's important to recognize the structural features that make a substance act as an acid or a base.
The "descriptive" chemistry covered here usually gets squeezed out of modern chemistry courses, but it's interesting stuff and well worth knowing.
