Is there a primer I could read to refresh my knowledge of basic chemistry? I prefer the written format. A 50-100 pages document would be ideal. I don't mind chemical equations and math.
I was thinking about something less expensive and beefy than one of those $100+, 800 pages textbooks. [1] [2] [3] [4] Something closer in format to the MIT Essential Knowledge Series.
You can get used, earlier-edition college textbooks very cheaply. The question sets are changed each edition but the text is not meaningfully. I buy some for fun reading and some for reference.
