These are two indicators:
- Methyl orange: pH of 3.1 (color red) to 4.4 (color yellow)
- Phenolphtalein: pH of 8.2 (colorless) to 10.0 (color purple)
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
The pH range of xylenol orange indicator is typically around 4.8 to 8.3. It changes color between these pH values, making it useful for pH determination in this range.
The PH range of Xylenol Orange indicator is between 3.2 and 4.4. In PH ranges, a 7.0 is a neutral range.

NH3 is titrated with HCl which indicator is suitable?
Methyl orange is a suitable indicator for the titration of NH3 with HCl because the pH range for the color change of methyl orange (pH 3.1-4.4) corresponds well with the equivalence point of the reaction between NH3 and HCl (pH 4.74).
What color range did the substance show when tested with the indicator paper?
Indicator paper is a common name for litmus paper. Litmus paper tests pH. The color range is red to purple, when red is very acidic (pH of 1) and purple is very basic (pH of 14). In between the spectrum are the other pH values. Green is neutral (a pH of 7). Yellow and orange are acids also, ranging from a pH of 2-6. Teal and blue are bases, with pH ranging from 8-13. Hope this helps!
What can you use in place of bromophenol blue?
Methyl orange or phenolphthalein can be used as alternatives to bromophenol blue in certain experiments requiring a pH indicator. It is important to consider the specific requirements of the experiment and the pH range of the indicator being used.
The pH range over which an indicator changes color is its?
The pH range over which an indicator changes color is its transition range. This is the range of pH values over which the indicator molecule shifts between its acidic and basic forms, resulting in a visible color change.
What are the colors of a carrot indicator?
A carrot indicator can range from orange to yellow, depending on the pH of the solution it is measuring. In acidic conditions, it may appear yellow, while in basic conditions it may turn orange.

Methyl orange is a suitable indicator for the titration of NH3 with HCl because the pH range for the color change of methyl orange (pH 3.1-4.4) corresponds well with the equivalence point of the reaction between NH3 and HCl (pH 4.74).
What is the name of the indicator that gives you the range of colours for different pH numbers?
The indicator that gives you the range of colors for different pH numbers is called universal indicator. It is a mixture of several indicators that changes color over a wide pH range.

Why does the universal indicator change colour it had put vinegar?
Universal indicator changes color when exposed to vinegar due to the change in pH. Vinegar is acidic, which causes the indicator to shift to a color that corresponds to that level of acidity.

Is methyl orange the indicator used in the titration of na2co3 against hcl solution?
No, methyl orange is not commonly used as the indicator in the titration of Na2CO3 against HCl solution. Phenolphthalein is the indicator of choice for this titration, as the endpoint is at a pH of around 8.2, which is the color change range of phenolphthalein.
PH or acidity which is better indicator?
The acidity range is a part of the pH scale.
