✔Pink
〰️》Phenolphthalein, an acid-base indicator used to test the pH of a solution, turns pink due to the presence of a weak base. The indicator itself is a weak, colorless acid that forms pink anions when it dissolves in water. Although the anions are pink, the solution remains colorless in the presence of an acid.
