Unformatted text preview: NaCl(s) ⇌ Na + (aq) + Cl-(aq) o Unsaturated solution Concentration below max solubility o Supersaturated solution Concentration is greater than max solubility. No solid present. o We will always write these starting with solid as the reactant. Ex. • Mg(OH) 2 (s) ⇌ Mg 2+ (aq) + 2OH-(aq) K sp (solubility product) • K sp =[Mg 2+ ][OH-] 2 General Chemistry Lecture 102a In class notes for December 5, 2007 • Think about the solubility • Mg(OH) 2 (s) ⇌ Mg 2+ (aq) + 2OH-(aq) • Our solubility is defined based on the number of the reactant that is dissolved • Used a ICE table • So at equilibrium we get K sp =[s][2s] 2 = 4s 3 • Ksp is not equal to the solubility • Mg(OH) 2 is not in the equilibrium constant because it is a solid • Ksp solubility and vice versa o ONLY WORKS FOR INSOLUBLE SALTS o Because of ion pairing and non ideal behavior of solution • •...
