NOTE: You must memorize your solubility rules. See Table in chapter 3. PROBLEM: Which compound or compounds in each of the following groups is (are) expected to be soluble in water?(a) CuO, CuCl2, FeCO3 (b) AgI, Ag4PO4, AgNO3(c) K2CO3, KI, KMnO4 CuCl2 Step 2: Salts of halides with Ag+1, Pb+2 are insoluble. Most phosphates are insoluble. All salts of nitrates are soluble. AgNO3 Step 3: Most salts of alkali metals are soluble. Step 1: Most metal oxides are insoluble. Almost all salts of halides are soluble. Most carbonates are insoluble K2CO3, KI, KMnO4
