Odor threshold : No data available pH : No data available Melting point : 137 °C Freezing point : No data available Boiling point : No data available Methyl violet is an indicator that changes color over a range from pH=0.0 to pH=1.6. What is Ka of methyl viol? identify solutions with pH 6.5 (yellowish green), pH 7 (green) and, and pH 7.5 (bluish green). The methyl violet indicator remains violet above pH 2.0, gradually turning to yellow at pH 0.

Batch experiments were done to investigate the contact time, effect of pH, initial dye concentrations, and temperature. Langmuir and Freundlich isotherm models

At a pH of +1.0, the dye is green with absorption maxima at 420 nm and 620 nm, while in a strongly acidic solution (pH −1.0), the dye is yellow with an absorption maximum at 420 nm. The different colours are a result of the different charged states of the dye molecule.
