Answer:
Let’s write the balanced ionic equation for the reaction between silver ions (Ag⁺) and solid copper (Cu):
Half-Equations:
Copper Half-Equation: Cu → Cu²⁺ + 2e⁻
Silver Half-Equation: Ag⁺ + e⁻ → Ag (s)
Balanced Ionic Equation:
Combine the half-equations, ensuring that the number of electrons transferred is the same:
Copper Half-Equation (multiplied by 2): 2Cu → 2Cu²⁺ + 4e⁻
Silver Half-Equation: Ag⁺ + e⁻ → Ag (s)
Add the half-equations together:
Overall Balanced Ionic Equation: 2Ag⁺ + 2Cu → 2Cu²⁺ + Ag (s)
