What is the difference between the limiting law and the extended model?

The limiting law assumes ions are point charges and is best for very dilute solutions. The extended model uses `calculate_extended_activity_coefficient` to account for the physical size of ions, making it more accurate for moderate concentrations.

How do I calculate the Debye length?

You can use the `calculate_debye_length` tool by providing the ionic strength and the absolute temperature in Kelvin.

Can I calculate the mean activity coefficient for a salt?

Yes, use the `calculate_mean_activity_coefficient` tool. You will need the ionic strength, the product of the ion charges, the sum of the ion radii, and the temperature.

More Details Connect to Claude

This MCP server provides computational tools for electrolyte solution analysis using Debye-Hückel theory. It allows AI agents to calculate the Debye length, individual ion activity coefficients using the limiting law, and activity coefficients using the extended model which accounts for ion size. It also computes the mean activity coefficient for entire electrolyte salts.
