## Description

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.

## Tools

### calculate_debye_length
Determines the distance over which electrostatic interactions are significant in the solution

### calculate_extended_activity_coefficient
Calculates the activity coefficient for specific ions using a model that accounts for physical ion size

### calculate_limiting_activity_coefficient
Calculates the activity coefficient for specific ions using the most dilute approximation

### calculate_mean_activity_coefficient
Computes the average effective concentration effect for an entire electrolyte salt

## Frequently Asked Questions

**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.
