Methyl red is used as a pH indicator or for the identification of some bacteria.
Fractional distillation can be used to separate bromocresol green and methyl red. This is because the two have close boiling points.?æ
methyl red will disappear
The color of methyl orange is red. The color is red when the acetic acid is below pH 3.1.
3.1-4.4 from red to yellow
It would turn red

You use methyl red as a ph indicator for for the MRVP test.
Methyl orange is red under a pH=3,1 and yellow over a pH=4,4; methyl orange is useful for the titrimetric determination of acids concentration.
Methyl red differs from Phenolred (which is used in the fermentation test and the MSA plates) in that it is yellow at pH 6.2 and above and red at pH 4.4 and below. Phenol red turns yellow below a pH of 6.8. If you get a positive with methyl red and a negative with phenol red, the pH has to be between 6.7 and 6.1.
Methyl Red, methyl orange, bromophenol blue, phenolphthalein, thymolphthalein, bromocresol green, bromothymol blue are all used as acid base indicators.
