Suppose you are asked to determine the identity of a white solid. When you add water to the white solid, it dissolves and forms a clear solution. When you add a solution of Na, SO,, a white precipitate forms. Add Add H,O Na,SO, Determine the identity of the original solid. O PBCI, O MgCl, O ZNCI, O CaCl,

a. On the basis of the general solubility rules, choose the substance that is not likely to be soluble in water. NH4NO3: Rule 1 (an exception to the rule for nitrate salts). O (NH4)2S: Rule 6 (most sulfide salts are insoluble). O Cds: Rule 6 (most sulfide salts are insoluble). OCd(NO3)2: Rule 1 (an exception to the rule for nitrate salts). b. On the basis of the general solubility rules, choose the substance that is not likely to be soluble in water. Fe3(PO4)2: Rule 6 (most phosphate salts are insoluble). O K3PO4: Rule 6 (most phosphate salts are insoluble). O KNO3: Rule 1 (an exception to the rule for nitrate salts). Fe(NO3)2: Rule 1 (an exception to the rule for nitrate salts). c. On the basis of the general solubility rules, choose the substance that is not likely to be soluble in water. OKNO3: an exception to the rule for nitrate salts. No precipitate: Rule 3 (most chloride salts are soluble) Pb(NO3)2: an exception to the rule for nitrate salts. PbCl₂: an exception to the rule for…
