How can you predict whether a precipitation reaction will occur upon mixing two aqueous

Titrations of Polyprotic Acids  When one titrates a Polyprotic acid with a base, there is an equivalence point for each dissociation Solubility Products  Consider the equilibrium 2+at exists i2-a saturated solution of BaSO in wa4er o BaSO (s)4 Ba (aq) + SO (aq) 4  The equilibrium constant expression for this equilibrium is 2+ 2- o K = spa ][SO ] 4 Solubility  K sp not the same as solubility  Solubility is generally expressed as the mass of solute dissolved in 1L (g/L) or 100mL (g/mL) of solution, or in mol/L (M) Factors Affecting Solubility  The common-ion effect o If one of the ions in solution equilibrium is already dissolved in the solution, the equilibrium will shift to the left and the solubility of the salt will decrease  pH o Higher solubility for substances with basic anions by adding acids o The solubility of a salt whose anion is the conjugate base of a strong acid is unaffected by changes in pH o Solubility of a salt whose anion is the conjugate base of a weak acid will increase as pH decreases  Complex o Metal ions can act as Lewis acids and form complex ions with Lewis bases in the solvent  Amphoterism o Amphoteric metal oxides and hydroxides are soluble in strong acid or base, because they can act as either acids or bases Will a Precipitate Form  In a solution
