When the can is closed, the gas is under more pressure, and there are lots of bubbles because a lot of the gas is dissolved. The solubility product (Ksp) is used to calculate equilibrium concentrations of the ions in solution, whereas the ion product (Q) describes concentrations that are not necessarily at equilibrium. The next step is to set up an ICE table, where I stands for initial concentration, C stands for the change in concentration, and E stands for In the case of a simple 1:1 solid such as AgCl, this would just be the concentration of Ag + or Cl - in the saturated solution.
