2
Solubility PbCl 2 (s) ⇄ Pb 2+ (aq) + 2Cl - (aq)
3
Common Ion Effect BaSO 4 (s) ⇄ Ba 2+ (aq) + SO 4 2- (aq) What happens if you add Na 2 SO 4 to the solution? What if you just started with SO 4 2- ?
4
Compare the solubility of AgCl in pure water at 25˚C and the solubility of AgCl in a solution of 0.55M NaCl? K sp = 1.8 x 10 -10 at 25˚C.
5
Formation of complex ions Lewis acid + Lewis base Metal ions can act as a Lewis acid Examples of Lewis bases NH 3 CN - S 2 O 3 2- SCN -
6
Complex ions Ag + (aq) + 2NH 3 (aq) ⇄ Ag(NH 3 ) 2 + (aq)
7
Complex ions and solubility What happens if you have a beaker with AgCl (s) and NH 3 ?
