Chemistry 116 notes (3/29) **Prof. Bangbo Yan* (Chapter 4: Chemical Reactions) Ionic theory of solution and solubility rules • Ionic theory of solution ◊ Ionic theory ◊ : some substances produce freely moving ions when dissolved in water and can conduct an electric current in an aqueous solution. ◊ Electrolyte: substance that conducts electricity when dissolved in water EXAMPLE: NaCl ◊ Nonelectrolyte: substance that doesn’t conduct energy when dissolved in water. EXAMPLE: Sugar ◊ Weak electrolyte: substance that produces only a minimum amount of energy when dissolved in water. EXAMPLE: CH COOH3 • Ionization of acetic acid C3 COOH is a reversible reaction which means the reaction can occur in both ways. ◊ Electrolyte Chart Strong electrolyte Weak electrolyte Nonelectrolyte HCl CH 3OOH (NH 2 2O (urca) HNO 3 HF CH O3 (methanol) HClO 4 HNO 2 C 2 5H (ethanol) H2SO 4 NH 3 C 6 12(g6ucose) NaOH H2O (extremely weak) C 12O22s11rose) Ba(OH) 2 Ionic compounds • Solubility rules SOLUBLE ◊ Group 1A an ammonium compounds are soluble ◊ Acetates and nitrates are soluble ◊ Most chlorides, bromides and iodides are soluble • Exceptions: AgCl, AgBr, AgI Hg Cl , Hg Br , Hg I 2 2 2 2 2 2 HgBr H2, 2 PbCl 2 PbBr 2 PbI 2 ◊ Most sulfates are soluble • Exceptions: CaSO 4 Ag 2O 4 SrSO 4 Hg 2O 4 BaSO 4 PbSO 4 INSOLUBLE ◊ Most carbonates are insoluble • Exceptions: Group 1A carbonates and (NH ) CO 4 2 3 ◊ Most phosphates are insoluble • Exceptions: Group 1A phosphates and (NH ) PO 4 3 4 ◊ Most sulfides are insoluble • Exceptions: Group 1A sulfides and (NH ) S 4 2 ◊ Most hydroxides are insoluble • Exceptions: Group 1A hydroxides Ca(OH) ,2Sr(OH) , 2a(OH) 2
