- The anodic oxidation of NO−2 ion dissolved as AgNO2 in ACN, in the range − 12° to 68°C, is investigated using platinum electrodes. Single and multiple linear potential sweep and rotating disc electrode techniques are used. The electrochemical reaction is interpreted with the following sequence of reactions: rds (1) NO2 = NO2 + e (2) [2 NO2 ⇋ N2O4] (3) NO2 + NO2 = NO + NO3 (4) NO = NO- + e (5) NO+ + NO2 = N2O3 (6) [N2O3 ⇋ NO + NO2] Step (1) behaves as an irreversible step which at high potentials is diffusion controlled, while step (4) corresponds to a reversible charge transfer step. The chemical reactions are fast processes. The postulated reaction mechanism for the anodic discharge of the NO−2 ion implies the preferential reaction of the initial product with a NO−2 ion instead of a solvent molecule as it occurred with solutions employing other aprotic solvents.
