  1. Solubility Product Constant Ksp

  2. Ksp: review • What is the molar mass of H2O? 2) How many moles are in 18 g of NaCl? 3) How many g of CaCl2 are found in 2 L of a 3 M solution of CaCl2? 4) What is the concentration (in mol/L) of K+ when 2 L of 1.5 M KCl is mixed with 1 L of 3 M K2SO4? Hint: Add together the # mol K+ from each source to get total # mol K+. Divide this by total number of L.

  3. Ksp (solubility product) - background • Kspis similar to Kcor Keq 2) It deals with ions instead of gases, 3) one side of the chem. equation has a solid, which is ignored We have used Kc in equilibrium problems “K” indicates an equilibrium “c” indicates units are mol/L (in this course it will also indicate we are dealing with gases)

  4. There are other types of K: Ksp, Kw, Ka, Kb Each subscript immediately indicates some detail about the equilibrium Kw: equilibrium of water, Ka: acid, Kb: base Ksp: equilibrium between solid and ions

  5. Na+(aq) + Cl-(aq) NaCl(s) Ksp - background The equilibrium between solids and ions is different from the equilibrium between gases The equilibrium between solids and ions is a “phase” equilibrium (e.g. NaCl(aq)) Ksp deals with a phase equilibrium: (s)  (aq)

  6. Calculations Types of Questions • 1) Determining Individual Ion Concentration from Ksp • 2) Determining Ksp values from measured solubilities of ions
