You're absolutely right! This is a classic double displacement reaction that forms a precipitate. Here's how it breaks down:

The Reaction:

Lead chloride (PbCl₂) + Sodium sulfate (Na₂SO₄) → Lead sulfate (PbSO₄) + Sodium chloride (NaCl)

Explanation:

* Reactants:

* Lead chloride (PbCl₂) is a soluble ionic compound.

* Sodium sulfate (Na₂SO₄) is also a soluble ionic compound.

* Products:

* Lead sulfate (PbSO₄) is insoluble in water, meaning it forms a solid precipitate.

* Sodium chloride (NaCl) remains dissolved in the solution as ions.

The Precipitate:

The white, solid precipitate that forms is lead sulfate (PbSO₄). You can write the net ionic equation to focus on the formation of the precipitate:

Pb²⁺(aq) + SO₄²⁻(aq) → PbSO₄(s)

Key Point: Double displacement reactions occur when the cations and anions of two reactants switch partners. This is often driven by the formation of an insoluble product (precipitate).
