pH Indicator Ranges; pH Indicator Ranges (Ascending pH) Acid-base pH indicators are solutions that have a characteristic color at certain pH levels. They are used to visually signal the acidity or alkalinity of an aqueous (water-based) solution. pH indicators generally change color over a range of two pH units.
Apr 30, 2011· This is the key difference between bromocresol blue and bromocresol purple. Furthermore, another difference between bromocresol blue and bromocresol purple is that the bromocresol blue gives the colour changes at the pH range of 6 to 7.6 whereas the colour changes of bromocresol purple occur at 5.2 to 6.8 pH range.

The broad range of pH detection in the acid range, below the 7 pH mark, makes bromocresol green useful for testing the equivalence point of acidic solutions. Titrations are performed to determine the overall pH and concentration of a solution. An indicator is added to a solution based on whether it is acidic or basic and what pH is being tested .
These indicators are normally used over a fairly short range of pH values (indicated in the table above). As a pH indicator, bromothymol blue, for example, would be useful between from about pH 6.0 to pH 7.6. Other indicators work in different pH ranges.
