Pressure effects on solubility

Pressure generally increases the solubility of minerals. An accurate evaluation of the pressure effect on solubility may require that we consider both molar volumes and compressibilies of reactants and products. In the following problem we compare the solubility of celestite (SrS04) in a surface water at 1 bar pressure and 25°C to its solubility in groundwater at 6000 ft depth at a temperature of 75 C and pressure of 180 bars. The reaction of interest is SrS04(celestite) = + SO ". To...
