Bromocresol GreenMethyl Red Mixed Indicator is commonly used in analytical chemistry for acidbase titrations especially in determining alkalinity and acidity in water analysis.

The purpose of this mixed indicator solution is to provide a sharp and easily visible color change near a specific pH range making titration end points more accurate and easier to detect.

This indicator is a combination of bromocresol green and methyl red dyes dissolved in a suitable solvent and it changes color from greenish-blue to pinkish-red as the pH shifts from alkaline to acidic conditions.
