If the sewage is fully oxidized, the nitrogen is in the form of – (1) Nitrites (2) Ammonia (3) Nitramines (4) Nitrates

Description : If the sewage is fully oxidized, the nitrogen is in the form of – (1) Nitrites (2) Ammonia (3) Nitramines (4) Nitrates

Last Answer : (4) Nitrates Explanation: Oxidized forms of nitrogen include nitrite (NO2) and nitrate (NO3). Nitrogen mainly occurs in wastewater in this form. Because nitrite is easily oxidized to nitrate, nitrate is the compound predominantly found in groundwater and surface waters.
