A salt is an ionic compound made up of two oppositely charged ions a cation (positive) and an anion (negative). All salts are electrically neutral (the overall charge is zero). 2. When an ionic compound is soluble in water, ionic compound dissociates into: ions . 3. State whether each of the ionic compounds is soluble (s) or insoluble (ins) in water. Ionic Compound Soluble or Insoluble? Na 3 PO 4 Soluble. All salts containing Group I metals are soluble NH 4 Br Soluble. All salts containing an NH 4 + ion and non-bromide exceptions are soluble Fe(NO 3 ) 2 Soluble. All nitrate salts are soluble CaSO 4 Insoluble. Calcium sulfate is an exception CuS Insoluble. Most sulfide salts are insoluble PbCl 2 Insoluble. Lead (II) chloride is an exception to chlorides being soluble BaCO 3 Insoluble. Most carbonate salts are insoluble SnSO 4 Soluble. Not an exception for insoluble sulfates Ba 3 (PO 4 ) 2 Insoluble. Most phosphates salts are insoluble KOH Soluble. All salts containing Group I metals are soluble 4.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
