The acidity constant of the hydrogen chromate ion in the range 5-60° in water

Abstract

The equilibrium HCrO₄^-; ↔ CrO₄^2-+H⁺ in water has been studied by potentiometric and independent spectrophotometric methods between 5º and 60º. The thermodynamic quantities ΔS⁰, ΔH⁰, and ΔC_p have been evaluated.
