Acid-base indicators are substances whose color changes based on pH, often weak acids or bases themselves. The color change occurs when the indicator shifts between its acid form (HInd) and base form (Ind–). Each indicator has a specific pH range where it is most effective (e.g., phenolphthalein changes from colorless to pink around pH 8–10). They are commonly used in titrations to signal the endpoint.
