Product introduction: Methyl red is a glossy purple crystal or reddish brown powder, soluble in ethanol and acetic acid, almost insoluble in water; After long-term storage, the sensitivity of ethanol solution can be significantly reduced due to the esterification effect of carboxyl groups; The maximum absorption wavelength is 410nm, which can be used for live staining of protozoa; Acid-base indicator, pH color change range 4.4 (red) to 6.2 (yellow); Titrate ammonia, weak organic bases, and alkaloids, but not applicable to organic acids other than oxalic acid and picric acid; It can form a mixed indicator with bromocresol green and methylene blue to shorten the color gamut and improve the sensitivity of color change; Adsorption indicator for precipitation titration, such as titrating fluoride ions with thorium nitrate; Verify oxidants such as free chlorine and chlorite.
