How do I calculate overall formation constants?

You can use the `calculate_stepwise_constants` tool by providing an array of the individual stepwise formation constants.

Can this tool predict the concentration of specific complex species?

Yes, the `predict_species_concentrations` tool calculates the molar concentrations for the free metal, free ligand, and all resulting complex species at equilibrium.

How does complexation affect solubility?

By using `analyze_solubility_impact`, you can determine how the formation of soluble complex ions reduces the concentration of free metal ions, thereby increasing the solubility of the metal salt.

This MCP server provides a specialized chemical equilibrium engine for coordination chemistry. It allows AI agents to perform precise calculations for complexation reactions. Use calculate_stepwise_constants to derive overall formation constants from stepwise values, or predict_species_concentrations to determine the equilibrium distribution of metal ions, ligands, and complex species. You can also use analyze_solubility_impact to model how ligands increase the solubility of metal salts, and validate_complex_stability to assess the strength of specific coordination complexes.
