General description
The Griess reagent is used for the quantitative analysis of nitrite ions. Present nitrite (as well as nitrate) ions will form a pink diazo dye by diazonium coupling reaction with N-(1-Naphthyl)ethylenediamine. The concentration of nitrite (or nitrate) ions is proportional to the color intensity of the resulting red solution.
