2KNO₃(aq) + CaCl₂(aq) → 2KCl(aq) + Ca(NO₃)₂(aq)
Explanation:
* Reactants:
* KNO₃ (potassium nitrate) is a soluble salt that dissociates into K⁺ and NO₃⁻ ions in water.
* CaCl₂ (calcium chloride) is also a soluble salt that dissociates into Ca²⁺ and 2Cl⁻ ions in water.
* Products:
* KCl (potassium chloride) is a soluble salt that forms in solution.
* Ca(NO₃)₂ (calcium nitrate) is also a soluble salt that forms in solution.
Key Points:
* This reaction is a double displacement or metathesis reaction, where the cations and anions of the reactants switch partners.
* All the salts involved are soluble in water, meaning they dissociate into ions.
* The reaction occurs in solution, and the evaporation of water leaves behind the solid residue containing KCl and Ca(NO₃)₂.
Note: The reaction is an equilibrium reaction, but in this case, the products are also soluble salts, so the reaction is essentially complete.
