Copper(II) Inorganic Complex Stability Constants for Environmental Modeling

A critical review by Kipton J. Powell of the University of Canterbury provides recommended thermodynamic stability constants for copper(II) complexes with common environmental ligands. The data includes log10βp,q,r° values at standard conditions (25 °C, zero ionic strength) and parameters for calculating values at higher ionic strengths. Some reaction enthalpy values are also reported where available.

Use Cases

• Modeling copper(II) speciation in aquatic systems based on recommended stability constants.
• Calculating complex formation at varying ionic strengths based on provided equations and interaction coefficients.
• Incorporating thermodynamic data for inorganic copper complexes into geochemical models.

Strengths

• Data is a critical review, suggesting a curated and evaluated collection of constants.
• Provides specific parameters (log10βp,q,r°, ion interaction coefficients) for practical application.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
