What Is The Solubility Of Magnesium Sulphide In Water?

Magnesium sulphide has a low solubility in water. Its solubility product constant (Ksp) is 9.0 x 10^-12 at 25°C, indicating that only a small amount of the compound will dissolve in water to form its constituent ions. At saturation, the concentration of Mg2+ and S2- ions in solution is approximately 7.5 x 10^-6 mol/L. This means that, for practical purposes, magnesium sulphide can be considered insoluble in water. However, like most ionic compounds, its solubility can be increased by factors such as higher temperature, lower pH, or the presence of complexing agents or chelating agents.
