Apr. 10, 7:30-9:00 PM, 15- Equilibrium 16- Acids/Bases 17- Buffers/Indicators/Titrations 18- Solubility and Complex-Ion Equil. Problem Sets 5 - 8 2 18. Solubility and Complex Ion Equilibria olubility Product, K sp :- Equilibrium constant for ions in saturated aqueous solution. e.g., For Mg(OH) 2 (s) Mg 2+ (aq) + 2OH- (aq) K sp = [Mg 2+ ][OH- ] 2 = 1.8 x 10-11 hat is the solubility of Mg(OH) 2 in water, in mol/L and g/L? hat is the molar solubility of Mg(OH) 2 in 0.010M NaOH? 1.7 x 10-4 M; 9.6 mg/L 1.8 x 10-7 M 3 Common Ion Effect- the solubility of a slightly soluble ionic compound is lowered in the presence of a second solute that furnishes a common ion. 4 18. Solubility and Complex Ion Equilibria olubility Product, K sp :- Equilibrium constant for ions in saturated aqueous solution. e.g., For Mg(OH) 2 (s) Mg 2+ (aq) + 2OH- (aq) K sp = [Mg 2+ ][OH- ] 2 = 1.8 x 10-11 hat is the solubility of Mg(OH) 2 in water, in mol/L and g/L?...
