The numerical value of a solubility product K_(sp) is measured by experiment.For example, we could determine K_(sp) for CaSO_(4) by adding on excess of solid CaSO_(4) to water, stirring the mixture to give a saturated solution of CaSO_(4) and then measuring the concentration of Ca^(2+) and SO_(4)^(-) in the saturated solution. Value of K_(sp) are unaffected by the presence of other ions in soluiotn. At 27^(@)C experiemntal value of K_(sp) is 2.4 xx 10^(-5) M^(2). Solubility of CaSO_(4) solution in 0.02M aqueous Ca(NO_(3))_(2) solution
