Answer #1

Nitrification is a process of nitrogen compound oxidation.

2 NH4+ + 3 O2 2 NO2− + 2 H2O + 4 H+

The oxidation states are mentioned below:

-3           0            +3              -2

2 NH4+ + 3 O2 2 NO2− + 2 H2O + 4 H+

Here the oxidation state of N increases from -3 to +3 so the oxidation half reaction is:

2 NH4+ 2 NO2−

The oxidation state of O decreases from 0 to -2 so the reduction half reaction is:

3 O2 2 H2O
