Thank you, John Green.
This thirteen-and-a-half-minute-long video covers enough chemistry about water that if my students understood the entire video by the end of my year of chemistry, I would be pretty happy.
Because it's that saturated with knowledge, I don't know that I'd necessarily show it in one sitting in the classroom. It's dense, man, but it does a spectacular job explaining (and showing via animation) a whole lot of ideas about the chemistry of water. I'll list some of them...
- oxidizing (like bleach and hydrogen peroxide do)
- solutions (aqueous ones)
- solute
- solvent
- polar molecules
- polar and nonpolar molecules dissolving each other
- water dissolving ionic compounds
- electrolytes
- strong, weak, and non-
- moles
- concentration
- molarity
- molality
- diluting
