A student considers this skeleton redox equation (net redox reaction) in acidic solution, and four half-reactions. NO(g) + HSeO3(aq) N(g) + - N(g) + SeO (aq) Half-reaction equations: 1.HO(1) + HSO3(aq) - SeO(aq) + 4 H*(aq) + 2 e II. 2 H(aq) + NO(g) + 2 e N(g) + HO(l) III. H(g) + NO(g) + 2 e- N(g) + HO(l) IV. HSeO3(aq) + 4 H*(aq) + 2 O(g) + 6 e N 2. I and II The balanced half-reactions that would produce the net redox reaction are II and III II and IV rad I and III SeO,2(aq) + 3 H2O(I)
