Phenolphthalein 0.5% in 50% Isopropanol, Buy now Ready to use Indicator solution for reliable and reproducible results from Tristains indicators at Dawnscientific
Phenolphthalein is an organic chemical compound with the molecular formula C20H14O4 and a white crystalline solid state when pure. Phenolphthalein dissolves in a solvent to form a solution that finds its main application as a pH indicator. Phenolphthalein is dissolved in a mixture of a 50% IPA (isopropyl alcohol) and 50% water to form a 0.5% concentration solution. This is a clear and colorless solution that becomes colored as a result of the pH of the environment: it will remain colorless in acid solutions but become pink to fuchsia in alkaline solutions, with the color transition occurring in a pH of around 8.2 to 10.0. Phenolphthalein 0.5% in 50% isopropyl alcohol (IPA) is a chemical solution having many applications in scientific and industrial processes.
