Unlike [[Molality]] and [[Molarity]], solubility (<b>S</b>) only occurs at the saturation point. Therefore, the solution can only be a saturated solution (equilibrium exist between the solid and its hydrated ions) so solubility is a function of temperature. All solubility problem must specify the temperature of the solution to be investigated.<br> Solubility is usually expressed in units of g solute / g solvent where g solvent is usually "100.g H<sub>2</sub>O". Therefore, the equation for solubility is:<br> S = g solute / 100.g solvent , it should be written like: <br> So, Solubility problems are simply a set of ratios set equal to each other where one is the Solubility of the solution and the other is the gsolute over gsolvent: <br> S = gsolute / 100.g H<sub>2</sub>O = "X" gsolute / "Y" gH<sub>2</sub>O<br> <br> The problem needs to provide 2 of the three piece of information in the equation and you solve for the third.<br> http://www.tmcleod.org/Level1/solubilitytable.png
