WebbpH 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 ... WebbThe isoelectric point (pI, pH(I), IEP), is the pH at which a molecule carries no net electrical charge or is electrically neutral in the statistical mean.The standard nomenclature to represent the isoelectric point is pH(I). However, pI is also used. For brevity, this article uses pI.The net charge on the molecule is affected by pH of its surrounding environment …
