What is produced when copper displaces silver in a reaction?

• A. Copper nitrate and silver gas
• B. Copper metal and silver nitrate
• C. Copper and silver chloride
• D. Copper oxide and silver metal

Answer: (B)

In this reaction, when copper displaces silver, it typically occurs in an ionic solution where silver is present as silver ions (Ag⁺), and copper is more reactive than silver. According to the principles of single displacement reactions, a more reactive metal can replace a less reactive metal from its compound. When copper reacts with silver nitrate (AgNO₃), the reaction produces copper nitrate (Cu(NO₃)₂) and silver metal (Ag). The balanced chemical equation for this reaction can be represented as: \[ \text{Cu (s) + 2 AgNO₃ (aq) } \rightarrow \text{ Cu(NO₃)₂ (aq) + 2 Ag (s)} \] In this equation, solid copper displaces silver from silver nitrate, resulting in the formation of copper nitrate in solution and silver precipitating out as a metallic solid. Therefore, the correct answer is that copper metal and silver nitrate are produced in the reaction, confirming the answer choice.

When copper reacts with silver nitrate (AgNO₃), the reaction produces copper nitrate (Cu(NO₃)₂) and silver metal (Ag). The balanced chemical equation for this reaction can be represented as:

[ \text{Cu (s) + 2 AgNO₃ (aq) } \rightarrow \text{ Cu(NO₃)₂ (aq) + 2 Ag (s)} ]

In this equation, solid copper displaces silver from silver nitrate, resulting in the formation of copper nitrate in solution and silver precipitating out as a metallic solid. Therefore, the correct answer is that copper metal and silver nitrate are produced in the reaction, confirming the answer choice.
