A galvanic cell consists of a Zn/Zn^2+ half-cell and a Ag/Ag^+ half-cell. The standard reduction potentials are Zn^2+ + 2 e− → Zn(s) (E° = -0.76 V) and Ag+ + e− → Ag (E° = +0.80 V). Calculate the standard cell potential and discuss the spontaneity.
💡 Hint: Identify which half-reaction has the higher potential.
For a concentration cell formed with a salt solution containing different ion concentrations, calculate the cell potential using given concentrations and apply the Nernst equation.
💡 Hint: Make sure to establish concentrations and n value correctly before calculation.
