###### Question: For each of the following reactions, balance the chemical equation, calculate the emf, and calculate AGº at 298 K. (Use the smallest possible coefficients for H200), H(aq), and Ho (aq). These may be zero.) (a) In acidic solution copper(I) ion is oxidized to copper(II) ion by nitrate ion. Cu+(aq) + NO3(aq) + H+ (aq) → Cu2+(aq) NO(g) + emf H2O(1) AG k] (b) Aqueous iodide ion is oxidized to 12(s) by Hg22+ (aq). 1(aq) +_ Hg22+(aq) +_Ht _ 12(s)_Hg(1) + emf H20(1) AG (c) In basic solution Cr(OH)3(s) is oxidized to Cro42-(aq) by Clo"(aq). Cr(OH)3(s) + clo (aq) + OH(aq) → Cro42-(aq) emf ci(aq) + H20(1) AG
