Question

Which lead compound is the most soluble?
lead2acetate
lead2chloride
lead2hydroxide
lead2sulfide

Answer 1

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.
