For instance, methyl red is a common indicator that's red at pH of 5 and yellow at a pH Your pH strips will most likely be violet-bluish (pH 7) to start (see below).

Methyl violet's transition range is between 0.0 - 1.6. I know that the change in pH as you get near the equivalence point for a SA/SB titration is

Indicator Low pH color Transition pH range; Gentian violet (Methyl violet 10B) yellow: 0.0–2.0: Leucomalachite green (first transition) yellow: 0.0–2.0 Methyl violet 10B has six methyl groups. It is known in medicine as Gentian violet (or crystal violet or pyoctanin (e)) and is the active ingredient in a Gram stain, used to classify bacteria. It is used as a pH indicator, with a range between 0 and 1.6. 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.

What is methyl violet used for? Methyl violet is a family of organic compounds that are mainly used as dyes. Depending on the number of attached methyl groups, the color of the dye can be altered. Its main use is as a purple dye for textiles and to give deep violet colors in paint and ink. Is methylene blue a pH indicator?
