I was going to make a joke about how Austria is landlocked, how did we come up with the idea of making an ocean water standard.

Apparently the IAEA which is headquartered here set that standard, for anyone else curious.

you can of a lot of molecules though. and tgat is classically "physics" rather than "chemistry". Classical chemistry is reactiona between atoms or molecules to form new ones.

If you get deeper into it, the lines between chemistry and physics blur anyways.
