What the Expert Says:

I think you mean "dissolves" rather than melts, which happens with heat vs what happens when these things are added to water or another solvent.

So, to find out, get 4 glasses, fill them with, say 200 ml of H2O, then add, say, 100 grams of a salt to each of the glasses, and start observing and keeping time. Good luck.
