Chemistry. Chemistry Virtual Textbook. Acid-base chemistry can be extremely confusing, particularly when dealing with weak acids and bases.
This set of lessons presents an updated view of the Brønsted-Lowry theory that makes it easy to understand answers to common questions: What's the fundamental difference between a strong acid and a weak acid? Can acid A neutralize base B? Why are some salts acidic and others alkaline? Creative Chemistry AS and A Level Stuff. Practical Chemistry. Dynamic Periodic Table.
