Scientific Basis of the Galvanic Cell Calculator
The Galvanic Cell Calculator is based on the Nernst equation, a cornerstone of electrochemistry that describes the cell potential under non-standard conditions. The cell potential (\( E_{\text{cell}} \)) is calculated as:
\[ E_{\text{cell}} = E^\circ_{\text{cell}} - \frac{RT}{nF} \ln Q \]
Where:
- \( E^\circ_{\text{cell}} \): Standard cell potential (V), calculated as \( E^\circ_{\text{cathode}} - E^\circ_{\text{anode}} \).
- \( R \): Gas constant (8.314 J/(mol·K)).
- \( T \): Temperature in Kelvin.
- \( n \): Number of electrons transferred in the redox reaction.
- \( F \): Faraday’s constant (96485 C/mol).
- \( Q \): Reaction quotient, based on ion concentrations.
For a cell reaction like \( \text{Zn} + \text{Cu}^{2+} \rightarrow \text{Zn}^{2+} + \text{Cu} \), the reaction quotient is:
\[ Q = \frac{[\text{Zn}^{2+}]}{[\text{Cu}^{2+}]} \]
The calculator uses standard electrode potentials from thermodynamic databases:
- Cu²⁺/Cu: +0.34 V
- Zn²⁺/Zn: -0.76 V
- Ag⁺/Ag: +0.80 V
- Pb²⁺/Pb: -0.13 V
These values and the Nernst equation ensure accurate, peer-reviewed calculations.
