C) gains 2 Ag+(aq) + 2 e-------> 2 Ag (s) Here, two silver ions (silver with a positive charge) are being reduced through the addition of two (2) electrons to form solid silver. The abbreviations "aq" and "s" mean aqueous and solid, respectively. We can now combine the two (2) half-reactions to form a redox equation: Ag+(aq) + SO 2(g) + H 2O(l) → Ag(s) + SO 4 2-(aq) + H 3O +(aq) Determine oxidation state of each element in reaction: Ag+ + SO 2 + H 2O → Ag + SO 4 2-+ H 3O+ +1 +4 -2 -2 -2 -2+1 +10+6 Review: Balancing Redox Reactions Example: Ag+(aq) + SO 2(g) + H 2O(l) → Ag(s) + SO 4 2-(aq) + H 3O +(aq) Ag is reduced (+1 → 0) S is oxidized (+4 → +6 1 Oxidation-Reduction Chemistry Chem 36 Spring 2002 2 Definitions nRedox reactions involve electron transfer: Cu (s) + 2 Ag+ (aq) ﬁ Cu2+ (aq) + 2 Ag (s) Lose e-= Oxidation Gain e-= The silver cation, Ag +, reacts quickly with halide sources to produce the insoluble silver halide, which is a cream precipitate if Br- is used, a white precipitate if Cl − is used and a yellow precipitate if I − is used.
