Stability of the calcium dioxalate complex

J R Burns, B Finlayson, A Smith

    Investigative Urology
    |September 1, 1980

    Area of Science:

    • Geochemistry
    • Solution Chemistry
    • Chemical Thermodynamics

    Background:

    • Calcium oxalate minerals, such as whewellite, are relevant in biological systems and geological formations.
    • Understanding the speciation of calcium in oxalate-rich solutions is crucial for various chemical and environmental processes.

    Purpose of the Study:

    • To determine the thermodynamic stability constant of the calcium dioxalate complex, Ca(C2O4)2(2-).
    • To investigate the effect of oxalate concentration on the solubility of calcium oxalate (whewellite).

    Main Methods:

    • Solubility measurements of [45Ca]whewellite in solutions with varying oxalate concentrations at 38°C.
    • Analysis of solubility data using ionic equilibrium equations.
    • Nonlinear least-squares fitting to estimate the stability constant.

    Main Results:

    • Whewellite solubility increased with oxalate concentrations above 10 mM.
    • The thermodynamic stability constant for the calcium dioxalate complex was determined to be 17.32 ± 1.1 M⁻¹.

    Conclusions:

    • The formation of a calcium dioxalate complex influences the solubility of whewellite.
    • The determined stability constant provides quantitative insight into calcium-oxalate interactions in solution.
