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
common ion effect
coupled equilibria
selective precipitation
titration curve
mixture of appreciable amounts of a weak acid-base pair the pH of a buffer resists change when small amounts of acid or base are added
buffer capacity
buffer
molar solubility
titration curve
amount of an acid or base that can be added to a volume of a buffer solution before its pH changes significantly (usually by one pH unit)
