Nitrates and nitrites are families of chemical compounds containing atoms of nitrogen and oxygen. Occurring naturally, nitrates and nitrites are critical to the continuation of life on the earth, since they are one of the main sources from which...

Nitrates are compounds containing the anion NO3-. Nitrites are compounds containing NO2-. Nitrates are salts derived from nitric acid and nitrites are salts or esters of nitrous acid. All nitrates are readily soluble in water. Many nitrates are ionic...

Together with NITRATE, is part of the nitrogen cycle. Sodium nitrite is used as a food preservative, especially for cured meats. Chloramination can lead to the formation of nitrites in water distribution systems. Nitrite is toxic to humans because it...

This ion appears in the intermediate stage of wastewater stabilization. Excess ammonia is oxidized by microorganisms to nitrite. Concentrations are usually less than 1 mg/L –N in effluents. In surface and groundwater supplies concentrations will...

The nitrite ion is NO2−. The anion is bent, being isoelectronic with O3. A nitrite is either a salt or an ester of nitrous...

A Nitrite-free Meat-curing System In North America alone some nine billion pounds of meat are cured annually using sodium nitrite. As a curing agent nitrite performs the following multiple functions: 1. It produces the cooked cured-meat pigment, dinitrosyl ferrohemochrome, which gives...
