Re: Water and salt - Part of that is because the two things are so interested in combining with one another that they don't want to let go to combine with anything else. That's why salt (an
ionic solid) takes such a high temperature to melt and why you have to rip water (a
covalent one) apart with electricity (electrolysis) to get it back to its component parts.
Me, I've always wondered just exactly how violent the reaction between Cesium (or Francium!) and Flourine would be. Their respective
electronegativities are
so far apart that it promises to be particularly vigorous.
Yes, I'm a nerd. Knowing chemistry is fun. Don't believe me? Remember this--don't clean aluminum with muratic (hydrochloric) acid. Trust me on this one.
