Phenol red is a stable red crystal that can be found in air. Its chemical formula is C19H14O5S. Phenol red, also known as phenolsulfonphthalein or PSP, serves as a pH indicator that alters its color based on the pH of a solution. The color transition is clear and easily understandable, shifting from yellow under acidic conditions to red in neutral and fuchsia in basic conditions. When dissolved in a neutral or slightly basic aqueous solution, a 0.04% concentration of phenol red appears as a red liquid. Its distinct color changes in various pH environments make it a valuable tool for pH level monitoring. A 0.04% solution of phenol red represents a slightly higher concentration of this pH indicator dye, commonly utilized in a range of scientific and industrial settings.
