Description

Metanil Yellow is used as indicator. Metanil yellow is useful in spectrophotometric methods to determine the presence of trace amounts of nitrates and nitrites in solution. The method utilizes the fact that potassium bromate can catalyze the discoloring of Metanil yellow which can then be analyzed by spectrophotometry.
