If you're not a chemist, you may have trouble finding some chemicals for chemistry experiments and projects. There are a lot of chemicals that are commonly available, but usually they aren't labelled with a chemical name so you might not recognize them. Have you found a good source of chemicals or do you know of pure compounds that are sold as common household chemicals? If so, share your information with others. Share Your Finds

Manganese Dioxide

Inside batteries, wash the impurities out and let the MnO2 settle at the bottom, pour the solution out leaving the manganese dioxide behind, and boil it off. Not sure if it's pure, but it's good enough

Found as drain openers (although often with contamination in the form of aluminium granules and sodium salts). Some paint supply shops sell them in the form of pellets as paint stripper (this is usually pure sodium hydroxide).

Copper sulfate & Sulfuric acid

Copper sulfate can be found as root kill, usually 99% purity, also Rooto makes sulfuric acid drain cleaner that is almost lab grade with no inhibitors.

an excellent source for quality chemical

The web site United Nuclear Scientific Supply sells many ACS reagent grade chemicals in small quantities. The amounts are small enough to be classified as ORM-D, so there are no hazmat charges for shipping. I have ordered there several times and am very satisfied with their service.
