NH₄Cl(aq) + AgNO₃(aq) → AgCl(s) + NH₄NO₃(aq)
Here's a breakdown of the reaction:
* Reactants:
* Ammonium chloride (NH₄Cl) is a colorless ionic compound.
* Silver nitrate (AgNO₃) is also a colorless ionic compound.
* Products:
* Silver chloride (AgCl) is a white, insoluble solid that precipitates out of solution.
* Ammonium nitrate (NH₄NO₃) is a colorless ionic compound that remains dissolved in the solution.
Explanation:
This reaction is a double displacement reaction, meaning the positive and negative ions switch partners. The silver ions (Ag⁺) from silver nitrate react with the chloride ions (Cl⁻) from ammonium chloride to form silver chloride (AgCl), which is insoluble in water and forms a white precipitate. The ammonium ions (NH₄⁺) and nitrate ions (NO₃⁻) remain in solution as ammonium nitrate (NH₄NO₃).
Key Points:
* The reaction is balanced, meaning there are equal numbers of each type of atom on both sides of the equation.
* The state symbols indicate the physical state of each substance: (aq) for aqueous (dissolved in water), and (s) for solid.
* This reaction can be used to test for the presence of chloride ions in a solution.
