When iron(II) sulfate (FeSO₄) and sodium carbonate (Na₂CO₃) are mixed in an aqueous solution, a double displacement reaction occurs, resulting in the formation of:

* Iron(II) carbonate (FeCO₃), a pale green precipitate.

* Sodium sulfate (Na₂SO₄), which remains dissolved in the solution.

The balanced chemical equation for this reaction is:

FeSO₄(aq) + Na₂CO₃(aq) → FeCO₃(s) + Na₂SO₄(aq)

Here's a breakdown of the reaction:

* Iron(II) sulfate (FeSO₄) is a soluble salt.

* Sodium carbonate (Na₂CO₃) is also a soluble salt.

* Iron(II) carbonate (FeCO₃) is an insoluble solid and therefore precipitates out of the solution.

* Sodium sulfate (Na₂SO₄) remains dissolved in the solution as it is soluble.

The reaction is a classic example of a precipitation reaction where an insoluble product is formed.
