Slightly SolubleThere is no standard rule forthe solubilityvalueInsoluble means S <0.1g/100gH,O,AgCl, AgBr, Agl, BaSOSlightly soluble: S = 0.1~1 g/100gH,O,PbCl CaSO4,Hg,SO4 etcSoluble means S> 1g/100gH,0IonicCompoundsare strong electrolytes which dissociatecompletelyin aqueous solution?
5 Slightly Soluble There is no standard rule for the solubility value. Insoluble means S < 0.1g/100gH2O ,AgCl, AgBr, AgI, BaSO4 Slightly soluble: S = 0.1 ~ 1 g/100gH2O ,PbCl2 CaSO4 , Hg2 SO4 etc. Soluble means S > 1g /100gH2O Ionic Compounds are strong electrolytes which dissociate completely in aqueous solution
