The indicator used for a color change at the equivalence point depends on the type of titration being conducted. In strong acid-strong base titrations, phenolphthalein is commonly used, as it changes from colorless to pink around a pH of 8.2 to 10. For weak acid-strong base titrations, methyl orange or bromothymol blue might be more appropriate, as they change color at lower pH levels. The choice of indicator should match the pH at the equivalence point of the specific reaction being analyzed.
