mark me as brainliest answer and thanks me for the reply

Explanation:

Sodium hydroxide is a base, and it was in the pitcher at the beginning, so when added to the phenolphthalein in beakers 2 and 4, it turned pink (top half of the graphic). The equilibrium shifts right, HIn decreases, and In- increases. ... Under acidic conditions, the phenolphthalein indicator is colorless.
