Practice Problem: ICE Box Calculations
Sometimes when we do equilibrium calculations, we have to use an ICE box. Don't worry it won't be chilly, it stands for initial, change, and equilibrium. Let's use this technique to calculate some equilibrium concentrations!

Solubility Product Constant (Ksp)
We've learned that some ionic solids are totally water insoluble, but in fact this is a slight oversimplification. Even such solids will dissolve to some minuscule degree, and we can measure this, and do calculations with it. Let's learn...

Chemical Equilibria and Reaction Quotients
Many chemical reactions don't just go one way, they go forwards and backwards. Once there is balance between the two, this is an equilibrium. And we need to be able to predict how much stuff there will be at equilibrium! Get ready to...
