Indicator choice. The visual transition range is the main factor in selection of pH indicator. Indicator solubility also is important. When using the indicator for an acid-base titration, ease of identifying the color change and slope of the titration curve must be considered. Figure 1 illustrates titration of a strong acid with a strong base.

Phenolphthalein pH Range and Colors. The two main colors of phenolphthalein are colorless and fuchsia, which is a pink-purple-red color, depending on the indicator concentration. Phenolphthalein is colorless under acidic, neutral, and slightly basic conditions. It's pink between pH values of 8.3 and 10.0 and then becomes colorless again at pH.

pH Ranges of pH Indicators. pH indicators are specific to the range of pH values one wishes to observe. For example, common indicators such as phenolphthalein, methyl red, and bromothymol blue are used to indicate pH ranges of about 8 to 10, 4.5 to 6, and 6 to 7.5 accordingly. On these ranges, phenolphthalein goes from colorless to pink, methyl.
