I was told that dd-water will superheat when heated up in a microwave because of a lack of ions.
1) Doesn't water auto-ionize? I asked this; the answer was it auto-ionizes "too slowly" in dd-water to prevent superheating.
2) This begs the question: what are the kinetics of the auto-ionization of water? What's the rate?
3) This also begs the question - what is superheating? What does ions have anything to do with superheating?
