Methyl Red Application:
1.Methyl red is one of the commonly used acid-base indicators, the usual concentration is 0.1% ethanol solution, pH4.4 (red)-6.2 (yellow).
2.Also used for in vivo staining of protozoa.
3.It can be combined with bromocresol green and methylene blue to form a mixed indicator to shorten the color change range and improve the sensitivity of color change.
4.adsorption indicator for precipitation titration, such as titration of fluoride ion with thorium nitrate.
5.detection of free chlorine, chlorite and other oxidants.
