Balance the following skeleton reaction in basic solution (if the coefficient is 1, put 1; if the coefficient is 0, put 0) and identify the oxidizing and reducing agents. For the oxidizing and reducing agent, enter numbers and +/- directly for superscripts and subscripts. (eg. enter HCO3- for HCO3-, Cu2+ for Cu2+) AsO43- (aq) + NO2- (aq) AsO2- (aq) +NO3- (aq) AsO43-(aq) + NO2-(aq) + H2O(l) + OH- AsO2-(aq) + NO3-(aq) + OH- + H2O(l) (basic)
