One mole of loses 10 moles of electrons to form a new compound Y. Assuming that all the nitrogen fro — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

In $N_2H_4$, hydrogen is +1, so the initial O.S. of N is -2. Total charge contributed by the two N atoms = -4. When the molecule loses 10 electrons, the net charge on the nitrogen framework becomes $-4 - (-10) = +6$. Since there are 2 nitrogen atoms, the average O.S. of N in Y is $+6 / 2 = +3$.
