I think one way to improve this site would be to include an abbreviation glossary for newcomers. I have run across multiple abbreviations that I have no idea mean or that could have dual meanings. One example is the use of SH. At first I just assumed it was sodium hydroxide, but then I realized it could be sodium hypochlorite. Maybe it's just my inexperience but I find this pretty confusing. Anyway that's just my two cents.
