Which one chemical is used as a food additive, in the industrial synthesis of PVC window frames and to clean metals? One molecule: hydrochloric acid. Yes, that’s the stuff we also all carry in our stomach to help digest the food that we eat.


Salt - “Think of the love that you eat when you salt your meat”.

These are the closing phrases of the song Sodium Chloride composed by the American singing sisters Kate & Anna McGarrigle. Their song describes how a little atom of chlorine, wandering around tin the sea, meets an atom of sodium; through their 'chemical love' they become sodium chloride. We call this compound table salt.
