Is this oxidation or reduction: (NO3)- ---> NO (this is a half reaction I took from the full equation)
The Attempt at a Solution
At first, I got the oxidation states of each of the atoms
For (NO3)- N has an oxidation state of 5+ and O has an oxidation state of 6-.
for NO N has an oxidation state of 2+ and O has an oxidation state of 2-.
and then I look at the charge of the whole compound.
It goes from - to 0.
therefore, i concluded that this is a oxidation equation.
but it is actually a reduction equation
Did I overlook something?
