Question

In a reaction, 4 moles of electrons are transferred to one mole of HNO3. The possible product obtained due to reduction is

Answer 1

Dear Student


In HNO₃ , the oxidation state of Nitrogen, N is:

[+1 + (x) + (3 * (-2))] = 1 + x - 6 = x - 5

Therefore, x = +5


Now, according to the question, 4 moles of e^- are transferred to 1 mole of HNO_​3

which means that the oxidation state of Nitrogen, N will get reduced by 4

Thus, the oxidation number of N becomes, x = 5 - 4 = +1

Thus, the possible reaction would be:

HNO_​3 -------> 0.5 N₂O

(+5) ----------> $\frac{1}{2}$ (+1) (2) [=+1]
