r/AskChemistry is a subreddit with 48k members. The community frequently discusses chemistry, reaction, acid, chemicals, and reactions, and the most common flair used is general, inorganic/phyical chem, organic 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.
