|---|---|---|---|---|---|
| common ion effect | effect on equilibrium when a substance with an ion in common with the dissolved species is added to the solution; causes a decrease in the solubility of an ionic species, or a decrease in the ionization of a weak acid or base | ||||
| complex ion | ion consisting of a central atom surrounding molecules or ions called ligands via coordinate covalent bonds | ||||
| coordinate covalent bond | (also, dative bond) covalent bond in which both electrons originated from the same atom | ||||
| coupled equilibria | system characterized the simultaneous establishment of two or more equilibrium reactions sharing one or more reactant or product | ||||
| dissociation constant | (Kd) equilibrium constant for the decomposition of a complex ion into its components | ||||
| formation constant | (Kf) (also, stability constant) equilibrium constant for the formation of a complex ion from its components | ||||
| Lewis acid | any species that can accept a pair of electrons and form a coordinate covalent bond | ||||
| Lewis acid-base adduct | compound or ion that contains a coordinate covalent bond between a Lewis acid and a Lewis base | ||||
| Lewis acid-base chemistry | reactions involving the formation of coordinate covalent bonds | ||||
| Lewis base | any species that can donate a pair of electrons and form a coordinate covalent bond | ||||
| ligand | molecule or ion acting as a Lewis base in complex ion formation; bonds to the central atom of the complex | ||||
| molar solubility | solubility of a compound expressed in units of moles per liter (mol/L) | ||||
| selective precipitation | process in which ions are separated using differences in their solubility with a given precipitating reagent | ||||
| solubility product constant (Ksp) | equilibrium constant for the dissolution of an ionic compound |
