Answer:
The correct answer is A) Pb(C₂H₃O₂)₂ + Li₂SO₄
Step-by-step explanation:
- All salts of Na, K and ammonium are soluble.
- All nitrates are soluble.
- All chlorides are soluble, with the exception of AgCl, Hg₂Cl₂, PbCl₂ and CuCl.
- All sulfates are soluble, with the exception of CaSO₄, SrSO₄, BaSO₄, PbSO₄, HgSO₄, Hg₂SO₄ and Ag₂SO₄.
- All hydroxides are poorly soluble, with the exception of alkaline hydroxides, Sr(OH)₂, Ba(OH)₂ and NH4(OH)
- All carbonates are poorly soluble, with the exception of alkaline carbonates and ammonium carbonate.
- All sulfides are poorly soluble, with the exception of alkaline sulfides, alkaline earth sulfides, and ammonium sulfide.
The reaction A is:
Pb(C₂H₃O₂)₂ + Li₂SO₄ ⇒PbSO₄ + 2 LiC₂H₃O₂
Lead sulfate is a slightly soluble solid, therefore it precipitates.
