Introduction
In this reaction, 4 moles of electrons are transferred to one mole of HNO3, which acts as an oxidant. We need to determine the possible reduction product that can be formed as a result of this reaction.
Explanation
To determine the possible reduction product, we can consider the reduction half-reactions of HNO3. HNO3 can be reduced to various nitrogen-containing compounds, and the number of electrons transferred can help us determine the product.
Half-Reactions:
1. HNO3 + 3e- → 1/2 N2O (Nitrous oxide)
2. HNO3 + 4e- → NO2- + 2H2O (Nitrite ion)
Analysis:
Given that 4 moles of electrons are transferred, we need to find a reduction half-reaction that involves the transfer of 4 moles of electrons.
From the two half-reactions mentioned above, we can see that the second half-reaction involves the transfer of 4 moles of electrons. Therefore, the possible reduction product is 1 mole of NO2.
Conclusion:
The possible reduction product when 4 moles of electrons are transferred to one mole of HNO3 is 1 mole of NO2 (option 3).
