Where to find MSDS and SDS on the Internet General Sites These sites have large collections of MSDS and are a good place to start your search. [Top] [General Sites] [Governmental] [Chemical Companies] [Pesticides] [Misc] Government and Non-Profit Sites The first two sites return all sorts of chemical information; the remainder are written more for humans rather than corporate lawyers and are good sites for non-chemists to find information. Chemical Manufacturers and Suppliers The best place to start if you have a bottle from that particular manufacturer! Pesticides (herbicides, insecticides, fungicides, nematicides, rodenticides etc.) A great place to start for farmers, home gardeners or someone who got too close to a crop dusting plane. Miscellaneous Look here for manufacturers whose primary business is not chemicals.

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? How do buffers work? What governs the shapes of titration curves? This complete rewrite of the previous 1996 pdf document is now organized into seven lessons covering all aspects of the subject. Much emphasis is placed on the practical aspects of calculations, including how to deal with quadratic equations and how to judge when approximations are appropriate.

General Chemistry for Students The basics What is Chemistry all about? An introduction to chemical science. Preliminaries: stuff you should know before delving too far into Chemistry - tutorials covering the following topics: classification and properties of matter, density and buoyancy, energy, heat and temperature, units and dimensions, measurement error, significant figures and rounding off (these last three topics are identical with the first three in the lesson described immediately below.) Matter and measure: all about units, uncertainty, significant figures,and how to deal with experimental error. Units and conversion factors - see below LeChatelier's Principle interactive quiz by Gary Bertrand ChemBalancer and Element Quiz - four games you can play online. Balancing Chemical Equations - 1270 reactions, organized into easy, intermediate, and "challenging".
