Problem: Complete and balance the following equation:As2O3(s) + NO3-(aq) → H3AsO4(aq) + N2O3(aq) (acidic solution)

FREE Expert Solution

Balancing the redox reaction in acidic media:

As2O3(s) + NO3-(aq) → H3AsO4(aq) + N2O3

Step 1: Separate the whole reaction into two half-reactions:

As2O3 (s)   H3AsO4(aq)                                         NO3 (aq) → N2O3 (aq)

Step 2: Balance the non-hydrogen and non-oxygen elements first:

As2O3 (s)   2 H3AsO4(aq)                                    2 NO3 (aq) → N2O3 (aq)
