What is the standard cell potential (E°) for a galvanic cell composed of a zinc electrode and a copper electrode?

What is the standard cell potential (E°) for a galvanic cell composed of a zinc electrode and a copper electrode?

Step 1: Identify the half-reactions for the zinc and copper electrodes. Zinc (Zn) will oxidize and copper (Cu) will reduce.
Step 2: Look up the standard reduction potentials (E°) for both half-reactions. For Cu²⁺/Cu, E° = 0.34 V. For Zn²⁺/Zn, E° = -0.76 V.
Step 3: Use the formula for standard cell potential: E° = E°(Cu²⁺/Cu) - E°(Zn²⁺/Zn).
Step 4: Substitute the values into the formula: E° = 0.34 V - (-0.76 V).
Step 5: Simplify the equation: E° = 0.34 V + 0.76 V.
Step 6: Calculate the final value: E° = 1.10 V.
