adduct
product containing at least one coordinate covalent bond
common ion effect
effect of adding to a solution a salt that has an ion in common with a solute, causing the equilibrium to shift, lowering the solubility of the original solute so that it precipitates out of solution
complex ion
molecule consisting of a central ion to which other groups of molecules or ions are bound
coordinate covalent bond
covalent bond in which the shared electrons come from only one of the atoms
formation constant (Kf)
equilibrium constant for a complex ion formation
ion product (Qsp)
constant analogous to the solubility product constant but calculated from initial concentrations or other ion concentrations when the reaction is not at equilibrium
Le Chatelier's principle
principle that states that a change in the temperature, pressure, or concentration of a component will cause the equilibrium condition of a chemical system to change in a way that reduces the change
Lewis acid
electron-pair acceptor in a Lewis acid-base reaction
Lewis base
electron-pair donor in a Lewis acid-base reaction
ligand
ion or molecule that bond to a central metal atom or ion as part of a coordination complex
molar solubility
molarity of a compound in a saturated solution
saturated solution
solution that contains the maximum amount of dissolved solute normally possible at a certain temperature
saturation point
concentration at which no more solute dissolves in a solution for a given temperature and pressure
selective precipitation
separation technique for compounds that share a common ion but have different solubilities and are precipitated out of solution
solubility product constant (Ksp)
equilibrium constant for a solid in an aqueous solution
strong electrolyte
ionic compound that dissociates completely into its component ions in solution
supersaturated solution
solution that contains more than the maximum amount of dissolved solute normally possible at a certain temperature
unsaturated solution
solution that contains less than the maximum amount of dissolved solute normally possible at a certain temperature
weak electrolyte
ionic compound that only partially dissociates into its component ions in solution
