Type I problems:  These are problems for which you are given the conditions at equilibrium.  You just plug-and-chug.

Type II problems:  These are problems for which you are given the conditions leading up to equilibrium.  In these cases, you must assume x moles, M, or atm or reaction occurs.  It is suggested that you set up a table with the concentrations of all species before equilibrium and after equilibrium. You need to use algebra.   See the lab manual for more details and examples.

* ...or the pH of the molar solubility.
