Applications :
Analytical Chemistry: Cresol Red Sodium Salt finds applications in analytical chemistry for the detection and quantification of certain substances. It can be used as a colorimetric reagent to form complex reactions with metal ions or other organic molecules, allowing their qualitative or quantitative analysis.pH Indicator: Cresol Red Sodium Salt is widely used as a pH indicator due to its pH-sensitive color change. It transitions from yellow in acidic solutions (pH < 7.2) to red in alkaline solutions (pH > 8.8). The transition range typically lies between pH 7.2 and 8.8. It is commonly employed in laboratory settings to monitor pH changes in chemical reactions or to determine the acidity or alkalinity of various solutions.Biological and Cell Culture Applications: Cresol Red Sodium Salt can be used in biological and cell culture applications. It can be added to cell culture media to monitor and maintain the pH of the growth environment, ensuring optimal conditions for cell viability and growth.Titration Indicator: Cresol Red Sodium Salt can be used as an indicator in acid-base titrations to determine the endpoint of the reaction. The color change of the indicator helps in identifying the equivalence point during the titration process, ensuring accurate and precise measurements.Educational and Demonstration Purposes: Cresol Red Sodium Salt is often used in educational laboratories and demonstrations to teach pH concepts, acid-base chemistry, and the principles of chemical indicators. Its distinct color change and ease of use make it an effective tool for visualizing pH changes and engaging students in scientific experiments.
