r/AskChemistry is a subreddit with 52k members. The community frequently discusses chemistry, reaction, acid, chemicals, and reactions, and the most common flair used is general, organic chem, medicinal chem, practical chemistry, and biochem.
We are chemists and scientists who help demystify molecular behavior and apply discipline to naughty, wayward reactions, with a dash of wit & humor.
From basic principles to advanced topics, we welcome discussion of all levels of chemistry & related fields (eg. pharmacology, biology, physics).
Share links, images, and citations to enhance discussions.
Expect science-fueled answers, colorful discussion, and perhaps a touch of electron-bullying.
