It is used as a pH indicator, with a range between 0 and 1.6. Methyl violet changes from yellow to blue-violet. The midpoint of this range, pH 0.80 - is where 50% of the methyl violet is still yellow, and 50% is now blue-violet.

When pH is higher than 3, the solubility of methyl violet are essentially unchanged. Methyl violet has a molecular weight of 393.96 g mol −1. The structure of this dye is shown in Fig. 1 (Dai, 1994).

the removal of methyl violet 2B cationic dye. Afterpreparation, the obtained composite was characterized by applying several instrumental techniques, includingX-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy and determination of pH at the point of zero charge. Methyl orange is PH indicator used in titration because of its clear and distinct color variance at different pH values. Methyl orange shows red color in acidic medium and yellow color in basic medium.
