Which of the following represents the correct products of the reaction: AgNO3 (aq) + KCl (aq) → ?

• A. AgCl (s) + KNO3 (aq)
• B. AgCl (aq) + KNO3 (s)
• C. AgNO3 (aq) + KCl (aq)
• D. AgK (s) + NO3Cl (aq)

Answer: (A)

Verified step by step guidance

1. Identify the type of reaction: This is a double displacement (or metathesis) reaction where the cations and anions of the reactants exchange partners.
2. Write the reactants with their ions: AgNO3 dissociates into Ag\^{+} and NO3\^{-}, and KCl dissociates into K\^{+} and Cl\^{-}.
3. Exchange the ions to form the products: Ag\^{+} pairs with Cl\^{-} to form AgCl, and K\^{+} pairs with NO3\^{-} to form KNO3.
4. Determine the physical states of the products: AgCl is insoluble in water and precipitates as a solid (s), while KNO3 remains dissolved in aqueous solution (aq).
5. Write the balanced equation with correct products and states: AgNO3 (aq) + KCl (aq) → AgCl (s) + KNO3 (aq).
