== Waste Disposal == 

 I have been wondering if it would be alright to include copyrighted information from www.sigmaaldrich.com about molecular weights, solubility, etcetera (SigmaAldrich has alot of chemistry stuff, but the site terms of use states:  
 "Limited Use. Subject to these Terms, you are authorized to access and use the Site (a) for the purposes of making purchasing decisions with regard to products offered for sale on the Site, for administering orders placed on the Site, for education and related research, and for background information on products offered for sale on the Site, and (b) at the sole discretion of Sigma-Aldrich." , but the statement: 
 "education and related research, and for background information on products offered for sale on the Site" might allow it to be put on wikipedia). If everyone agrees that the quote I picked out works for allowing us to put it on wikipedia, then I will edit chemistry entries to include that information as I see fit.
