Which of the following is the correct molecular equation for the precipitation reaction that occurs when solutions of silver nitrate (AgNO3) and sodium chloride (NaCl) are mixed?

• A. AgNO3(aq) + NaCl(aq) → AgCl(aq) + NaNO3(s)
• B. AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq)
• C. AgNO3(aq) + NaCl(aq) → AgNO3(s) + NaCl(aq)
• D. AgNO3(aq) + NaCl(aq) → NO REACTION

Answer: (B)

Verified step by step guidance

1. Identify the reactants and products in the given chemical equation. The reactants are silver nitrate (AgNO3) and sodium chloride (NaCl), both in aqueous form.
2. Understand the concept of a precipitation reaction. A precipitation reaction occurs when two soluble salts react in solution to form an insoluble solid, known as the precipitate.
3. Determine the solubility of the products formed. Silver chloride (AgCl) is known to be insoluble in water, meaning it will form a solid precipitate, while sodium nitrate (NaNO3) remains soluble in water.
4. Write the correct molecular equation for the precipitation reaction. The correct equation should show the formation of the insoluble precipitate AgCl(s) and the soluble product NaNO3(aq).
5. Review the options provided and select the equation that correctly represents the formation of the precipitate. The correct molecular equation is: AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq).
