Phenolphthalein

Filed Under P 

A compound that changes color in the presence of acids or bases and is thus used as an indicator in titrations. It’s got a “phth” plus it breaks the “i before e” rule which makes it totally rebellious. The ee sounds at either end of the word really carry you through the weird middle in order to bring the word together. It’s unfortunate that it doesn’t come up more in conversation!
