What is the chemical reaction of phenolphthalein and sodium hydroxide?

Phenolphthalein reacts with sodium hydroxide to form a pink color, indicating the presence of a base. The chemical reaction involves the deprotonation of phenolphthalein by hydroxide ions to form an ionized molecule with a pink hue.


Why you use phenolphthalein as a indicator in titration of NaOH with HCL?

Phenolphthalein is normally used for this reaction as it accurately displays the end point of the reaction, turning colorless as soon as it reaches the end point of the reaction. If carrying out this reaction, be careful, as the change is usually quite sudden. The color exhibited should be pink (or "fuchsia") at the beginning of the reaction. As it progresses, it should become lighter in color, until it becomes colorless suddenly.
