Applications of aqueous equilibria

Presentation - 90 pages - Physics

When AgNO3 is added to a saturated solution of AgCl, it is often described as a source of a common ion, the Ag+ ion. By definition, a common ion is an ion that enters the solution from two different sources. Solutions to which both NaCl and AgCl have been added also contain a common ion; in this...
