The Reaction:

Iron(II) chloride (FeCl₂) reacts with silver nitrate (AgNO₃) in an aqueous solution to produce iron(II) nitrate (Fe(NO₃)₂) and solid silver chloride (AgCl).

Balanced Chemical Equation:

FeCl₂(aq) + 2AgNO₃(aq) → Fe(NO₃)₂(aq) + 2AgCl(s)

Explanation:

* FeCl₂(aq): Iron(II) chloride is dissolved in water, forming an aqueous solution.

* AgNO₃(aq): Silver nitrate is also dissolved in water, forming an aqueous solution.

* Fe(NO₃)₂(aq): Iron(II) nitrate is formed as a product and remains dissolved in the water.

* 2AgCl(s): Silver chloride is formed as a white precipitate (solid) and falls out of the solution.

Key Points:

* Double Displacement Reaction: This is a classic double displacement reaction where the cations and anions of the reactants switch places.

* Precipitate Formation: The formation of the solid silver chloride precipitate (AgCl) is the driving force behind this reaction.

* Spectator Ions: The nitrate ions (NO₃⁻) and the chloride ions (Cl⁻) are considered spectator ions because they do not directly participate in the formation of the precipitate.
