Thermodynamic properties of aqueous aluminate ion, AI(OH)₄⁻(aq)

Abstract

The heat effect of the reactions between metallic aluminum and NaOH(aq) solution of various concentrations were calorimetrically determined. Combining with the thermodynamic properties of related substances led to the thermodynamic properties of Al(OH)₄⁻(aq) as following:
