Number of moles of electrons taken up when 1 mole of $NO_{3}^{-}$ ions is reduced to 1 mole of $NH_{2} OH$ is

Answer:

Solution:

$N + 5 O_{3}^{-} ⟶ N (- 1) H_{2} OH$

In NO₃⁻, the oxidation state of N is +5.

In NH₂OH, the oxidation state of N is -1.

The change in oxidation state is $+ 5 - (- 1) = 6$ .

Therefore, 6 moles of electrons are taken up.
