Solubility
Solubility, also known as saturation concentration, is the proportion of a designated solute that dissolves in a solvent, ranging from essentially zero for insoluble substances to infinity for miscible ones.
Solubility product
The solubility product, Ksp, is the equilibrium constant for a slightly soluble ionic solid dissolving into its ions; precipitation occurs when the ion product Q exceeds it.
Soluble boron
Soluble boron, called chemical shim or a soluble poison, is boric acid dissolved in a pressurized water reactor's coolant to absorb neutrons and control core reactivity, reducing reliance on control rods.
Soluble reactive phosphorus
Soluble reactive phosphorus (SRP), also called molybdate reactive phosphorus or dissolved reactive phosphorus, is a filtered phosphorus measurement used in limnology as an estimate of phosphate available to algae.
