Solubility of gypsum vs ph
WebGypsum. Gypsum should be surface-applied and not incorporated. If soil pH is less than 5, the application might be harmful to plants present at the time of the application. In this situation, it would be recommended to use liming to correct soil pH, and then reevaluate for gypsum application as needed. WebFeb 2, 2024 · The equilibrium constant for a dissolution reaction, called the solubility product ( Ksp ), is a measure of the solubility of a compound. Whereas solubility is usually expressed in terms of mass of solute per 100 mL of solvent, Ksp is defined in terms of the molar concentrations of the component ions. In contrast, the ion product ( Q) describes ...
