1. What is Cell Potential in Potentiometry?

Definition: Cell Potential in Potentiometry is the amount of work energy needed to move a unit of electric charge from a reference point to a specific point in an electric field.

Purpose: It helps in determining the electrochemical potential difference between two electrodes in a potentiometric cell.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ E_{cell} = (R_P \times I_P) + V_{app} \]

Where:

\( E_{cell} \) — Cell Potential (volts)
\( R_P \) — Resistance in Potentiometry (ohms)
\( I_P \) — Current in Potentiometry (amperes)
\( V_{app} \) — Applied Potential in Potentiometry (volts)

Explanation: The cell potential is calculated by multiplying the resistance by the current and then adding the applied potential.

3. Importance of Cell Potential Calculation

Details: Accurate measurement of cell potential is crucial in electrochemical analysis, pH measurements, and various industrial processes.

4. Using the Calculator

Tips: Enter the resistance in ohms, current in amperes, and applied potential in volts. The calculator will compute the cell potential.
