What species are produced at the electrodes under standard conditions? Ag+(aq) + e- → Ag(s) E° = +0.80 V Silver chloride is a chemical compound with the chemical formula Ag Cl. This white crystalline solid is well known for its low solubility in water (this behavior being reminiscent of the chlorides of Tl + and Pb 2+). Upon illumination or heating, silver chloride converts to silver (and chlorine), which is signaled by grey to black or purplish Aa Ab Ac Ad Ae Af Ag Ah Ai Aj Ak Al Am An Ao Ap Aq Ar As At Au Av Aw Ax Ay Az . Tell Us What You Think × Ag + (aq) + 2NH 3 (aq) ⇌ Ag(NH 3) 2 + (aq) is known to be K c = 1.105x10 7.

In the reaction. Sn2+(aq) + 2 Ag+(aq) → Sn4+(aq) + 2 Ag(s), the oxidizing agent is: A) gains electrons and is reduced. B) gains electrons and is oxidized. 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.
