Reef Chemistry Question of the Day 291
Here's a thought experiment.
Suppose I take three vials of RO/DI water and add a pure single chemical to each (might be the same or different chemicals or amounts in each vial). They do not seem to dissolve completely with mixing at room temperature, so I heat them up and mix some more. In all cases, the water goes clear as all the solids dissolve.
I let them cool overnight, and get vials that look like the picture below. One is clear (A), one is a little cloudy (B), and one is very cloudy (C).
Which one or two of these solutions is the most likely to be supersaturated when the picture was taken?
Good luck!
