Cresol Red Indicator 25gm

Original price was: $3,225.00.Current price is: $2,200.00.

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:

  1. Chemical Structure: Cresol Red is a sulfonephthalein dye with the molecular formula C21H18O5S.
  2. 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).
