Acquisition and Evaluation of Thermodynamic Data for Bieberite-Moorhouseite Equilibria at 0.1 MPa

Abstract

Published estimates for the equilibrium relative humidity (RH) at 25 °C for the reaction: bieberite (CoSO4·7H2O) = moorhouseite (CoSO4·6H2O) + H2O, range from 69.8 to 74.5%. To evaluate these data, the humidity-buffer technique was used to determine equilibrium constants for this reaction between 14 and 43 °C at 0.1 MPa. Reversals along fi ve humidity… (More)
