In this case, it is simpler to treat the nitrate ion as a unit with formula NO3− rather than separately balancing nitrogen and oxygen atoms on both sides of the equation. It can be seen that there is one nitrate ion on the left‐hand side but there are two on the right. Therefore we need to add 2 moles of nitric acid to the left‐hand side:
This has balanced the nitrate ions but not the hydrogen and oxygen atoms. There are 4 hydrogen atoms on the left‐hand side but only 2 on the right. There are also 2 oxygen atoms (apart from in the NO3− ion) on the left‐hand side but only 1 on the right. We therefore need to increase the number of water molecules to 2:
