phenol red turns yellow because it reacts to carbonic acid, which is a product of carbon dioxide mixing with H2O, or water. Phenol red is a Ph indicator, but not a very good one, so it reacts to strong acids (yellow orange) and strong bases (pink)
hope this helped!

If phenol red turns yellow in an experiment, it indicates that the solution has become acidic. Phenol red changes color based on the pH of the solution, with yellow indicating acidity, red indicating neutrality, and pink indicating alkalinity.
