About r/AskChemistry

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.

    1. Is there any reason why this wouldn't work?
    2. any chemist who can crack this one.. I’ve ruined linen/cotton clothes with Revive stiffener. Hot vinegar didn’t work.
    3. Is there a good rule of thumb for how much temperature changes rate of reaction?
