ICE table problems (Initial, Change, Equilibrium tables) come in two major types. In the first, they give you the equilibrium concentration of one of the compounds in a reaction, and you use the ICE table to find the concentrations of everything else. The other (much harder) type of problem is when they just give you the equilibrium constant, and that's when you end up with a quadratic equation and you have to do some fancy algebra.
Solubility Product -- Ksp
Remember a couple of chapters ago when we were talking about solubility rules, and we said that some stuff is "insoluble"? Yeah, that wasn't quite the full story. It turns out that even if something isn't a big fan of getting dissolved, that doesn't mean that the water won't be able to dissolve away a few atoms here and there. Using ICE tables and the solubility product (Ksp), we can figure out the molarity of the solution!
If you do not have an account, you should get one, because it is awesome! You can save a playlist for each test or each chapter, and save your "greatest hits" into a "watch right before the final" list (not that we recommend cramming, but when in Rome...)
