Methyl violet is a family of organic compounds that are mainly used as dyes. It appears yellow in solution of low pH (~0.15) and changes to violet with pH  The optimum conditions for methyl violet adsorption were pH 5 and contact time 30 min. Langmuir, Freundlich and Redlich-Peterson isotherm model were used  Methyl Violet test paper is used to test for narrow-range pH solutions, where the range is very low (0.2 to 2.0).Supplied in stoppered vials containing 100 strips  Methyl Violet. Safety Data Sheet Methyl Violet.

Methyl violet changes from yellow to blue-violet. The midpoint of this range, pH 0.80 - is where 50% of the methyl violet suppose we have a solution in which methyl violet is violet. This tells us that the pH of our unknown solution is greater than or equal to 2 because methyl violet turns violet at pH values of 2 or greater.
