Choosing Oxidation vs Reduction

Postby 104422816 » Sat Feb 06, 2016 2:46 pm

In the Gold Ring Dissolving example from page 52 of the course reader I see that we are using the reduction reaction for nitric oxide. But Im confused how you would know to do this seeing as you are putting a gold ring in a solution of nitric acid... so the nitric acid has to have already formed. If I were interpreting this question I would do the oxidation reaction of nitric oxide and the reduction of gold, which is wrong according to the solution.

Any help would be appreciated

It is because nitric oxide is a strong oxidizing agent and metals are usually reducing agent(it is hard to find metal ion with negative charges).
