pH Indicators

Subject: Chemistry

Book: General Chemistry

pH indicators are substances that change color depending on the acidity or basicity of a solution. Common indicators include litmus, phenolphthalein (colorless in acid, pink in base), and bromothymol blue. Each indicator has a characteristic pH range where the color change is most apparent. Indicators are useful for rapid pH estimation or as endpoints in acid–base titrations.
