Another post has got me thinking that maybe there should be a thread where people list sources of elements and compounds that can be gotten under generic names. Also, it could include relative purity etc.
For instance -
XYZ Salt is a source of sodium chloride but it may have inert compounds in it according to the label.
Or
ABC Drain Cleaner is a source or sodium hydroxide but my analysis of it has proven it to not be pure.
Where would we put such a thread? The Advertisements and Testing Forum and Chemistry in Everyday Life seem to be likely candidates.
How say you admins, et al?
