Not syncing C https://east.cengagenow.com/ilm/take Assignment/takeCXPCompliantActivity.do?locator=assignment take On the basis of the general solubility rules, predict the identity of the precipitate that forms when aqueous solutions of the following substances are mixed. If no precipitate is likely, indicate which rules apply. 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, PbCly, and Hg, 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 (s?), carbonate (CO3), and phosphate (PO, 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 a. Iron(II) chloride, FeCl2, and ammonium sulfide, (NH4)2S O NHACI O FeCl2 O No precipitate: Rule 2 (most salts of NH + are soluble) and an exception to the rule for sulfides. O Fes O (NH4)2S b. Copper(ll) nitrate, Cu(NO3)2, and potassium phosphate, K3PO4 O K3PO4 O No precipitate: Rule 1 (most nitrate salts are soluble) and an exception to the rule for sulfides. o Cu3(PO4)2 O KNO3 O Cu(NO3)2 c.
