The solubility rules are listed in table below. General Rules for Solubility of lonic 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 Hg₂ Cl2. 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 (CO32), and phosphate (PO4) 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. K₂SO3 PbSO3 Na₂SO3 C8₂SO3 b. BaF₂ CsF KF NaF C.KF CaF₂ NaF CsF
