WebAcid-Base Indicators: In an acid-base titration, we often use an indicator to approximate the equivalence point of the reaction. For example, phenolphthalein is a commonly used indicator. In solutions with a pH lower than 8.3, it is colorless; in solutions with a pH greater than 8.3, it obtains a pink-to-red color. WebThe supernatant is collected, then the pH adjusted to 4.1–4.5 with 10% (v / v) ammonium hydroxide.
