WebIn this colorimetric method, use for drinking water, wastewater and seawater, nitrate is reduced to nitrite with hydrazine sulfate. The diazonium reagents then react with the nitrite to produce a red color. The intensity of the color is proportional to the original amount of nitrate and nitrite present in the sample. WebFor the best stabilizer results, it should be used in water that has pH between 7.0-8.4 and total alkalinity of 240 ppm or lower. There are two possibilities: (1) If your pH pad turned purple as well, the sanitizer level is probably very high. Lower the sanitizer and then retest. (2) If your pH pad did not turn purple, the total alkalinity ...

WebAlkalinity is a measure of the capacity of water to neutralize acids. This is known as the buffering capacity of water, or the ability of water to resist a change in pH when acid is added. Alkalinity in water (with a pH of 7.0 or higher) is caused primarily by the presence of dissolved acid-neutralizing substances (alkali).
