General Rules for Solubility of Ionic Compounds (Salts) in Water at 25 °C. 1. Most nitrate (NO3-) salts are soluble. 2. Most salts of Na+, K+, and NH4+ are soluble. 3. Most chloride salts are soluble. Notable exceptions are AgCl, PbCl2, and Hg2Cl2. 4. Most sulfate salts are soluble. Notable exceptions are BaSO4, PbSO4, and CaSO4. 5. Most hydroxide compounds are only slightly soluble.* The important exceptions are NaOH and KOH. Ba(OH)2 and Ca(OH)2 are only moderately soluble. 6. Most sulfide (S2-), carbonate (CO3 2-), and phosphate (PO4 3-) salts are only slightly soluble.* *The terms insoluble and slightly soluble really mean the same thing: such a tiny amount dissolves that it is not possible to detect it with the naked eye. On the basis of the general solubility rules, choose the substance that is not likely to be soluble in water. a. Cs2SO4, Na2SO4, PbSO4, K2SO4 b. PbSiO3, Cs2SiO3, Na2SiO3, K2SiO3 c. ZnS, Na2S, K2S, Cs2S
