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) WebA common ion is an ion that is already in the solution. Most of the time, the common ion effect makes it harder for a solute to dissolve. It can also change the pH of buffering …
