Shifting of absorption frequency of phenol red as a function of different solvents.
Accepted Answer
The absorption frequency of phenol red is shifted as a function of different solvents due to changes in the polarity of the solvent. In polar solvents, the phenol red molecule is more solvated, which leads to a decrease in the absorption frequency. In nonpolar solvents, the phenol red molecule is less solvated, which leads to an increase in the absorption frequency. This shift in absorption frequency can be used to determine the polarity of a solvent.
