(a)
Answer to Problem 48A
Nitrogen is reduced and Zinc is oxidized in this reaction.
Explanation of Solution
In Zinc nitride
In this reaction, oxidation state of N decreases from
Oxidation state of Zn increases from
(b)
Interpretation: From the given reaction, the element that is oxidized and the one that is reduced are to be identified.
Concept Introduction: In oxidation-reduction reaction, transfer of electron/s takes place. The transfer of electron, results in the formation of ions. In oxidation, loss of electron/s takes place and in reduction, gain of electron/s takes place.
