Description: Phenolphthalein 5g, 99%+. Phenolphthalein is often used as an indicator in acidbase titrations. For this application, it turns colorless in acidic solutions and pink in basic solutions. It belongs to the class of dyes known as phthalein dyes. Phenolphthalein is slightly soluble in water and usually is dissolved in alcohols in experiments. It is a weak acid, which can lose H+ ions in solution. The nonionized phenolphthalein molecule is colorless and the double deprotonated phenolphthalein ion is fuchsia. Further proton loss in higher pH occurs slowly and leads to a colorless form. Phenolphthalein ion in concentrated sulfuric acid is orange red due to sulfonation. Phenolphthalein's common use is as an indicator in acid-base titrations. It also serves as a component of universal indicator, together with methyl red, bromothymol blue, and thymol blue. In a highly basic solution, phenolphthalein's slow change from pink to colorless as it is converted to its Ph(OH)3 form is used in chemistry classes for the study of reaction kinetics. You will get 1 bottle containing 5g of phenolphthalein. That will be labeled and sealed shut. That will be bubble wrapped and placed in a box for shipping. That box will be labeled and taped shut before being shipped in a blue bubble wrap padded envelope with tracking included. If need be, I can take pics of the indicator in action for the listing. If you want to see that, just let me know.
