Jul 22,2025
What is Phenolphthalein?
Ah, Phenolphthalein! It’s one of those fancy words that often pops up in chemistry classes, but what does it really mean? Simply put, Phenolphthalein is a chemical compound often used as an acid-base indicator. When it comes to pH levels, this little marvel changes color, making it a staple in titrations and various laboratory experiments.
The Science Behind the Color Change
Now, let’s get a bit technical for a moment! Phenolphthalein is colorless in acidic solutions and turns pink in alkaline environments. This nifty trick happens because of a structural change in the molecule when it encounters different pH levels. So, if you’re mixing acids and bases, you can watch the magic unfold right before your eyes!
