Gypsum solubility in water at 25°C
@article{Lebedev2017GypsumSI, title={Gypsum solubility in water at 25°C}, author={A. L. Lebedev and V. L. Kosorukov}, journal={Geochemistry International}, year={2017}, volume={55}, pages={205-210} }
The analysis of published data and our experimental results showed that the existing estimates of gypsum solubility in water (Cm↑) at 25°C range from 0.0147 to 0.0182 M. Such a scatter (more than 20%) is the result of a combined influence of experimental conditions and ability of gypsum to form supersaturated solutions. This influence appears most noticeable during gypsum dissolution in a dispersed state. Under such conditions, equilibrium is determined with a precision of no better than ±4.5…
