Solubility product The Solubility product is related to SPARINGLY SOLUBLE SALTS ONLY!!!!! Examples are silver chloride‚ lead(II) chloride‚ calcium sulphate (in other words‚ it deals with salts commonly called insoluble salts) Consider a sparingly soluble salt MX Imagine the reaction that occurs when the solid is placed in water aMX (s) + H2O [pic] aMn+ (aq) + bXm- (aq) The equilibrium expression would be [Mn+]a [Xm-]b [MX]a [H2O]

Nais mong maabot lipunang malayaIbig mong makamit kaginhawaan ng madlaPaano mo mararating ang pangarap na itoKung bulag ka sa nangyayari sa paligid moTainga mo nama’y bingi sa karaingan ng taoDi mo pinapansin ang kanilang pagsusumamo.Pananaw mo sa buhay‚ bakit ba ganyan?Nais mong tumulong ikaw nama’y nag-aalinlanganIkaw ba’y natatakot iyong karapata’y ipaglaban?O iniisip mo lamang ang sarili mong kapakanan?Nasa pagkilos ang ating paglayaHindi sa pangarap at patunga-tungangaKung hindi ngayon kailan
