Definition: This calculator determines the number of cations and anions in a concentration cell with transference, based on electrochemical parameters.
Purpose: It helps electrochemists and researchers quantify ion transport in electrochemical cells with concentration gradients.
The calculator uses the formula:
Where:
Details: Understanding ion transport numbers helps in designing better electrochemical cells, batteries, and corrosion prevention systems.
Tips: Enter all required parameters. Ensure temperature is in Kelvin and activities are in mol/kg. All values must be positive.
Q1: What is the transport number of an anion?
A: It's the fraction of total current carried by the anion in the electrolyte.
Q2: How do I determine ionic activities?
A: Ionic activities can be calculated from concentrations using activity coefficients.
Q3: What's the typical range for transport numbers?
A: Usually between 0 and 1, with common values around 0.4-0.6 for many electrolytes.
Q4: Why is temperature important in this calculation?
A: Temperature affects ion mobility and the Nernst potential of the cell.
Q5: Can this be used for any electrolyte?
A: Yes, as long as you have accurate transport numbers and activity data.
