S15E1 - Buffer Solutions and the Common Ion Effect

WebThink about this: Strong acids and strong bases alone can never be used as a buffer solution because common ion effect does not apply to them. A mixture of a weak acid (or a weak base) and its conjugate gives the best buffer because common ion effect would apply. A mixture of two unrelated species (such as NaCl and KBr) where neither is ... WebWhy is Common Ion Effect Important? • To make buffers • Buffers resist changes in pH • When small quantities of strong acids or strong bases are added to a buffered solution, the changes in pH are small • Ex: blood (pH = 7.35-7.45) • Buffer: a weak acid and its salt (conjugate base) a weak base and its salt (conjugate acid)
