WebSolvated hydroxide and solvated protons are in equilibrium with liquid water. To define the concentration of these solvated ions in water, we usually use a value related to the equilibrium constant. The K w constant for water dissociation is 1 x 10-14. For acidic and basic solutions, pH and pOH are critical values. Solvation or dissolution is a kinetic process and is quantified by its rate. Solubility quantifies the dynamic equilibrium state achieved when the rate of dissolution equals the rate of precipitation. The consideration of the units makes the distinction clearer. The typical unit for dissolution rate is mol/s. See more Solvation describes the interaction of a solvent with dissolved molecules.
