Which lead compound is the most soluble?
1. All nitrates and acetates (ethanoates) are soluble. Lead forms water soluble compounds with nitrates and acetates. 2. All chlorides, bromides and iodides are soluble EXCEPT those of silver, lead and mercury(I). 3. All hydroxides are insoluble EXCEPT those of ammonium, barium and alkali metal (Group I) cations. Lead is a Group 14 heavy metal. (Exception)Lead hydroxide is slightly soluble at times but unstable and for the most part considered unsoluble in water. 4. All sulfides are insoluble EXCEPT those of ammonium, Alkali metal (Group I) cations and Alkali earth metal (Group II) cations. Lead is a Group 14 heavy metal. Hence, the most soluble lead compound is lead(II) acetate Pb(CH3COO)2.
