The reaction between sodium iodide (NaI) and silver nitrate (AgNO₃) is a double displacement reaction that produces a precipitate. Here's the balanced chemical equation:

NaI(aq) + AgNO₃(aq) → AgI(s) + NaNO₃(aq)

Here's a breakdown of the reaction:

* Reactants:

* Sodium iodide (NaI) is a soluble ionic compound.

* Silver nitrate (AgNO₃) is also a soluble ionic compound.

* Products:

* Silver iodide (AgI) is a yellow, insoluble ionic compound that precipitates out of solution.

* Sodium nitrate (NaNO₃) is a soluble ionic compound that remains dissolved in the solution.

Key points:

* The reaction occurs because silver iodide (AgI) is an insoluble compound, meaning it doesn't dissolve well in water. This causes it to form a solid precipitate.

* The other product, sodium nitrate (NaNO₃), is soluble and remains dissolved in the solution.

* The (aq) notation indicates that the compound is dissolved in water (aqueous solution).

* The (s) notation indicates that the compound is a solid (precipitate).
