Redox reactions are balanced in basic solutions using the

Question

Redox reactions commonly take place in acidic solutions. The could just as easily take place in basic solutions. This example problem shows how to balance a redox reaction in a basic solution.

Redox reactions are balanced in basic solutions using the same half-reaction method demonstrated in the example problem "Balance Redox Reaction Example". In summary:

1. Identify the oxidation and reduction components of the reaction.
2. Separate the reaction into the oxidation half-reaction and reduction half-reaction.
3. Balance each half-reaction both atomically and electronically.
4. Equalize the electron transfer between oxidation and reduction half-equations.
5. Recombine the half-reactions to form the complete redox reaction.

This will balance the reaction in an acidic solution, where there is an excess of H⁺ ions. In basic solutions, there is an excess of OH^- ions. The balanced reaction needs to be modified to remove the H⁺ ions and include OH^-ions.

Problem:

Balance the following reaction in a basic solution:

Cu(s) + HNO₃(aq) → Cu²⁺(aq) + NO(g)
