When you mix solutions of lead(II) acetate (Pb(CH₃COO)₂) and sodium carbonate (Na₂CO₃), you get a chemical reaction that produces a precipitate. Here's what happens:

The Reaction:

The lead(II) ions (Pb²⁺) from the lead(II) acetate react with the carbonate ions (CO₃²⁻) from the sodium carbonate to form lead(II) carbonate (PbCO₃).

Chemical Equation:

Pb(CH₃COO)₂(aq) + Na₂CO₃(aq) → PbCO₃(s) + 2CH₃COONa(aq)

What You Observe:

* A white precipitate forms: The lead(II) carbonate is insoluble in water, so it forms a solid that settles out of the solution.

* The solution becomes clear: As the lead(II) ions and carbonate ions are removed from the solution, it becomes clearer.

Important Note:

* This reaction is a double displacement reaction where the cations and anions of the two reactants switch places.

* Lead(II) carbonate is toxic and should be handled with care.
