Hanna Nitrite Test Kit HI-3873 Romania

Description

Hanna Nitrite Test Kit, Model No.: HI-3873, 100 Nitrite Tests, Made in Romania

Nitrites are intermediate oxidation state of nitrogen (in the oxidation of ammonia to nitrate or in the reduction of nitrate). Such oxidation/reduction may occur in the 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 the 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.
