Ammonia (NH3) is naturally produced through the decomposition of organic material as wellas being high in wastewater discharged to natural waters. In the environment it is oxidizedto form nitrite (NO2-), and nitrite is then oxidized to form nitrate (NO3-) in a process callednitrification. The balanced equations are given below:2NH3 + 3O2 → 2NO2- + 2H+ + 2H202NO2- + O2 → 2NO3-a) Assuming complete oxidation, what is the theoretical oxygen demand to convert100mg/L of ammonia to nitrate (i.e., how much oxygen is necessary)? Report youranswer as mg/L of O2.Answer: 376 mg/L O2b) This conversion process makes water more acidic. With reference to the equations forpH, explain why this occurs
