The pH range over which an indicator changes color.
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.
It depends on the sensitivity of the indicator you are using. There should be a guide with the indicator you are using. Litmus paper, which is the most common form of pH indicator, will change fairly constant across the pH scale, but a neutral (pH 7+/- 0.5 about) solution will normally not cause a change.
It indicates that the solution's range is above or below of its transition value. For example the transition value of phenolphthalein is around 9.0. Hence it shows a pink colour in basic solutions (pH>9) and colourless in acidic solutions.
The Ka for metacresol purple is not readily available. The pH range for this indicator is typically around 7.2 to 9.8 where the color transition occurs. At pH 9.0, metacresol purple would likely be predominantly purple, indicating a higher pH level.
If red rose indicator is used, acid will turn the indicator red, while alkaline solutions will turn the indicator green.

Sometimes one of the reactants in a titration act as an indicator; this is an internal indicator. An example is the volumetric technique of permanganometry.
To reset the service interval indicator on a 2002 VW Bora, turn the ignition to the "ON" position without starting the engine. Press the gas pedal three times within 10 seconds. After doing this, turn the ignition off and then back on to confirm that the service indicator has been reset. If the indicator still shows, repeat the process to ensure it has been properly reset.

There is always a transition in the middle of an interval
