Cresol Red is a pH indicator dye commonly used in titrations and other laboratory experiments to determine the pH of a solution. It changes color based on the acidity or basicity of the solution it is in. Here are its key characteristics:
- Chemical Structure: Cresol Red is a sulfonephthalein dye with the molecular formula C21H18O5S.
- Color Change: It transitions from yellow in acidic solutions (pH < 1.8) to red in neutral solutions (pH around 7.0), and then to purple in basic solutions (pH > 8.8).
Description
Uses of Cresol Red Indicator
- pH Indicator:
- Titrations: Cresol Red is often used in acid-base titrations to determine the endpoint of a reaction by indicating a pH change.
- pH Measurement: It helps in measuring the pH of solutions, especially in the intermediate pH range.
- Electrophoresis:
- DNA and RNA Analysis: Cresol Red can be used as a tracking dye in agarose and polyacrylamide gel electrophoresis to monitor the progress of nucleic acid migration.
- Cell Culture:
- pH Monitoring: In cell culture media, Cresol Red helps in monitoring the pH changes, which is crucial for maintaining optimal conditions for cell growth.
- Biochemical Assays:
- Enzyme Activity: It is used in various biochemical assays where pH change is an indicator of enzyme activity or reaction completion.
- Microbiology:
- Growth Media: In microbiological media, Cresol Red can indicate changes in pH due to microbial metabolism, aiding in the identification and study of microorganisms.
- Education and Demonstrations:
- Teaching Tool: In educational settings, Cresol Red is used to demonstrate acid-base reactions and pH changes in a visual and engaging manner.
