Naoh + phenolphthalein
Witryna14 cze 2024 · How does Naoh react with phenolphthalein? Explanation: When the sodium hydroxide, which is a base, is mixed with phenolphthalein, it turns pink. This happens because the base is neutralized in an acid solution, which causes the indicator to become colorless. All of the base is neutralized by the citric acid. Witryna1 wrz 2024 · What happens when phenolphthalein reacts with Naoh? Phenolphthalein is itself a weak acid. So when enough sodium hydroxide has been added to the acetic acid, such that there is no longer any unreacted acetic acid, the sodium hydroxide will then begin reacting with phenolphthalein.
