## How to use the Concentration Cell Calculator?

Our calculator is intuitive and user-friendly. Here's a breakdown of the terms you'll encounter:

**Standard Electrode Potential (E°)**- The potential difference when concentrations are at standard states.**Temperature (T in Kelvin)**- Generally at 298.15 K for most ambient conditions.**Number of Electrons (n)**- Dependent on the redox reaction taking place in the cell.**Concentrations**- Input the concentrations of the reduced and oxidized species.

## What is a Concentration Cell?

A concentration cell is an electrochemical setup where both electrodes are the same material, but they are immersed in solutions of different concentrations. This difference in concentration results in a potential difference, and this drives a current until equilibrium is reached.

## The Nernst Equation explained

To determine the potential of a concentration cell, we use the Nernst Equation:

E = E° - \dfrac{RT}{nF} \ln \left( \dfrac{[C_{\text{reduced}}]}{[C_{\text{oxidized}}]} \right)**E**- The cell potential**E°**- The standard electrode potential**R**- The universal gas constant (8.314 J/(mol K))**T**- Temperature in Kelvin**n**- Number of electrons transferred in the redox reaction**F**- Faraday's constant (approximately 96485 C/mol)**C**- Concentrations of the reduced and oxidized species respectively_{reduced}and C_{oxidized}

## Real-World Example

Let's say you have a concentration cell with a copper electrode in a 1.0 M Cu²⁺ solution connected to another copper electrode in a 0.01 M Cu²⁺ solution. Using the calculator:

- Input E° for the Cu/Cu²⁺ redox couple: +0.34 V.
- Temperature remains 298.15 K.
- Two electrons are transferred in the Cu/Cu²⁺ redox reaction, so n is 2.
- Input concentrations: 1.0 M for C
_{reduced}and 0.01 M for C_{oxidized}. - On calculation, you’ll obtain the potential difference driving the current in this cell!
