SB is oxidized=reducing agent (since losing electrons gives electrons to something else) NO3 is reduced=oxidizing agent (since gaining electrons requires taking them from someone else) Gain of oxygen is Oxidation Also, Sb went from neutral to +3. Increase in oxidation number is reduction. Nitrogen went from +6 to +2: Decrease in oxidation number is oxidation.
