Document Summary
We characterize solubility with a concept referred to as solubility product constant, or. Ksp: example scenario, caf2 (s) ca+2 + 2 f, ksp = [ ca+2 ] [f- ]2, evaluating ksp values, smaller ksp values are used to denote reactions that are low in solubility. Indicates that the solution has no more capacity to dissolve solute: larger ksp values are used to denote reactions that are high in solubility. Indicates that the solution has more capacity to dissolve solute: we are only able to compare ksp values when the compared reactions have the same number of dissolved ions, eg: cannot compare the ksp values between. Mg(oh)2 and feco3: mg(oh)2 will dissolve to form 3 dissolved ions where are feco3 will only form 2 dissolved ions, therefore we cannot directly compare the. Ksp values: we use ice tables in order to find solubilizes.
