Significance and Use

Nitrites are intermediate oxidation states of nitrogen (in the
oxidation of ammonia to nitrate or in the reduction of
nitrate). Such oxidation/reduction may occur in wastewater
of treatment plants and in natural waters during the
biological decomposition of nitrogen compounds. In small
quantities, it can cause methemoglobinemia among infants. Conversely, high levels are used to inhibit corrosion in
cooling towers. Nitrosation reactions of nitrites can yield
organic nitrosamines, which are known to be carcinogenic.
Note: mg/L is equivalent to ppm (parts per million).

Chemical Reaction

Nitrites react with a chronotropic acid reagent to form a pink
tint in the sample. The amount of color developed is
proportional to the concentration of nitrite present in the
aqueous sample
