Determine the oxidation state of nitrogen in NH3
Question
Determine the oxidation state of nitrogen in NH3
Solution
To determine the oxidation state of nitrogen in NH3, follow these steps:
-
Understand that the oxidation state is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic.
-
Hydrogen has an oxidation state of +1.
-
In NH3, there are three Hydrogen atoms, so the total oxidation state contributed by Hydrogen is +3.
-
The sum of oxidation states for all atoms in a molecule is zero.
-
Therefore, to balance out the +3 from Hydrogen, Nitrogen must have an oxidation state of -3.
So, the oxidation state of Nitrogen in NH3 is -3.
