These are two indicators:
1 and 2 toghether: pH of 3.1 red to 4.4 yellow, staying yellow up till 8.2,
then changing to greenish-purple from 8.2 at 10.0
crystal violet has a pH range of 7-8, which is basic.
The PH range of Xylenol Orange indicator is between 3.2 and 4.4. In PH ranges, a 7.0 is a neutral range.
pH range of Bromophenol Blue is 3.0-4.6
2-12
Methyl Orange indicator is made by dissolving .01 g of the powder into 100 ml of DI water. This gives and indicator for a pH range of 3.2-4.4 and goes from Red to Yellow.
The pH of 5% vinegar is between 2 and 3. The color of universal indicator in that range is reddish-orange.
An example of an indicator would be Phenol Red, or Universal Indicator. Depending on the pH range of the indicator and the pH range of the substrates you would use the appropriate indicator.
The colour of universal indicator is depending on pH pH Range and corresponding color: 0-3 red 3-6 orange yellow 7 green 8-11 blue 11-14 violet purple
Methyl orange changes colors while in the middle of the acidic range so it is only used as an indicator to determine just how acidic a solution is. Below a pH of 3.1 it is red. As pH gets higher it goes to an orange color until it gets above a pH of 4.4 where it will be yellow.

The US FDA lists the pH range of Florida Orange Juice as 3.3 - 4.15, and the pH range for California orange juice as 3.3 - 4.19.

The acidity range is a part of the pH scale.
pH range of indicator should be in the rapid pH gradient.

Methyl orange is a pH indicator having the chemical formula C14H14N3NaO3S.
The colour of universal indicator is depending on pH pH Range and corresponding color: 0-3 red 3-6 orange yellow 7 green 8-11 blue 11-14 violet purple
The pH range over which an indicator changes color.
