Phenolphthalein - Structure and Why Does it Change …
WebPhenolphthalein laxatives are often chocolate flavored, increasing palatability, but are only effective in primates and swine (Boothe, 2001 ). Bisacodyl is similar to phenolphthalein. Vegetable oil products contain irritant fatty acids such as ricinoleic acid in castor oil, linoleates in linseed oil and oliveates in olive oil. The doubly deprotonated (In 2-) phenolate form (the anion form of phenol) gives the familiar pink color. In strongly basic solutions, phenolphthalein is converted to its In (OH) 3− form, and its pink color undergoes a rather slow fading reaction [6] and becomes completely colorless when pH is greater than 13.
