Expert Tip
Ensure units are correctly formatted (e.g. Kelvin for gas temperatures and liters for volumes) to get chemically accurate outputs.
How this Calculator Works
This calculator allows you to solve Galvanic Cell problems dynamically. Adjust the input parameters using the sliders or selection menu below:
- Cathode Half-Cell (Dropdown selection, Default: Default)
- Cathode Concentration [C_cat] (M) (Range: 0.001 to 2.000, Default: 1.000)
- Anode Half-Cell (Dropdown selection, Default: Default)
- Anode Concentration [C_an] (M) (Range: 0.001 to 2.000, Default: 0.100)
- Temperature (T, °C) (Range: 0 to 100, Default: 25)
The results are computed instantly and updated in the results panel on the right.
Formula & Methodology
E° = E°cathode - E°anode
E = E° - (R * T) / (z * F) * ln(Q)
Q = [Anode]^an_coeff / [Cathode]^cat_coeff
E = E° - (R * T) / (z * F) * ln(Q)
Q = [Anode]^an_coeff / [Cathode]^cat_coeff
Where:
- Cathode Half-Cell: Parameter value.
- Cathode Concentration [C_cat]: Parameter value.
- Anode Half-Cell: Parameter value.
- Anode Concentration [C_an]: Parameter value.
- Temperature: Parameter value.
Step-by-Step Calculation Example
To calculate Galvanic Cell manually, follow these steps:
- Identify the input parameters. For example:
- Cathode Half-Cell = Default
- Cathode Concentration [C_cat] (M) = 1.000
- Anode Half-Cell = Default
- Anode Concentration [C_an] (M) = 0.100
- Temperature (T, °C) = 25
- Apply the formula:
E° = E°cathode - E°anode
E = E° - (R * T) / (z * F) * ln(Q)
Q = [Anode]^an_coeff / [Cathode]^cat_coeff - Verify the calculated value which is updated instantly in the results panel on the right.
