When sodium chromate (Na₂CrO₄) reacts with silver nitrate (AgNO₃), silver chromate (Ag₂CrO₄) precipitates out.

Here's the balanced chemical equation:

2 AgNO₃(aq) + Na₂CrO₄(aq) → Ag₂CrO₄(s) + 2 NaNO₃(aq)

* Ag₂CrO₄ is a bright red solid that is insoluble in water, hence it precipitates out of the solution.

* NaNO₃ is soluble and remains in the solution.

This reaction is a classic example of a double displacement reaction where the cations and anions of the reactants switch partners to form new products.
