Here's the balanced chemical equation for the reaction:
AgNO₃(aq) + KBr(aq) → AgBr(s) + KNO₃(aq)
Explanation:
* Silver nitrate (AgNO₃) and potassium bromide (KBr) are both soluble ionic compounds, meaning they dissolve in water and exist as ions.
* When mixed, the silver ions (Ag⁺) from silver nitrate react with the bromide ions (Br⁻) from potassium bromide.
* This reaction forms silver bromide (AgBr), which is insoluble in water and therefore precipitates out as a solid.
* The remaining ions, potassium (K⁺) and nitrate (NO₃⁻), remain in solution as aqueous potassium nitrate (KNO₃).
Key Points:
* The precipitate, silver bromide, is a pale yellow solid.
* This reaction is a classic example of a precipitation reaction, where two soluble ionic compounds react to form an insoluble product.
* The reaction is driven by the formation of the insoluble silver bromide.
