Its chemical formula is C\u2082\u2080H\u2081\u2084O\u2084, and it has a molecular weight of 318.32 g\/mol. Phenolphthalein appears as a white to yellowish - white crystalline powder. It is sparingly soluble in water but soluble in ethanol and ether. This product is supplied directly from the factory, ensuring high - quality and cost - effective procurement for our customers.<\/p>\n<h2 id=\"uses\">Usos del producto<\/h2>\n<p>\n        1. **Indicator in Chemistry**: Phenolphthalein is commonly used as an acid - base indicator in titration experiments. In acidic solutions, it remains colorless, while in basic solutions with a pH above approximately 8.2, it turns bright pink. This property makes it an essential tool in chemical analysis laboratories for determining the endpoint of acid - base reactions.<br \/>\n        2. **Medical Applications**: Historically, it was used as a laxative. However, its use in over - the - counter laxatives has been restricted due to potential health risks. Nevertheless, it still plays a role in some medical research and diagnostic procedures.<br \/>\n        3. **Industrial Dyeing and Testing**: In the industrial field, phenolphthalein can be used in certain dyeing processes and as a testing agent to detect the presence of alkaline substances on surfaces or in solutions.\n    <\/p>\n<h2 id=\"usage\">Uso del producto<\/h2>\n<p>\n        1. **As an Indicator in Titration**:<br \/>\n           - Prepare a solution of phenolphthalein by dissolving an appropriate amount in ethanol. A common concentration is 1% (w\/v).<br \/>\n           - Add a few drops of the phenolphthalein solution to the sample solution to be titrated.<br \/>\n           - Slowly add the titrant (either an acid or a base, depending on the nature of the sample) until the color change occurs. The appearance or disappearance of the pink color indicates the endpoint of the titration.<br \/>\n        2. **In Industrial Testing**:<br \/>\n           - For surface testing, dissolve phenolphthalein in a suitable solvent and apply it to the surface to be tested. If the surface contains alkaline substances, a pink color will appear at the contact points.<br \/>\n           - In solution testing, add a small amount of the phenolphthalein solution to the test solution and observe for color changes.\n    <\/p>\n<h2 id=\"case_studies\">Casos pr\u00e1cticos<\/h2>\n<p>\n        **Case 1: Acid - Base Titration in a School Laboratory**<br \/>\n        In a high - school chemistry class, students were conducting an acid - base titration experiment to determine the concentration of hydrochloric acid. They prepared a phenolphthalein indicator solution and added a few drops to the hydrochloric acid sample. As they slowly added sodium hydroxide solution (the titrant), the solution remained colorless until the equivalence point was reached. At that moment, a faint pink color appeared, indicating the endpoint of the titration. This allowed the students to calculate the concentration of the hydrochloric acid accurately using the volume of the titrant added.<br \/>\n        **Case 2: Industrial Surface Testing**<br \/>\n        A manufacturing company was producing metal components and needed to ensure that the surfaces were free from alkaline residues. They prepared a phenolphthalein - based testing solution and applied it to the metal surfaces. In some areas, a pink color appeared, indicating the presence of alkaline substances. The company was then able to take corrective measures, such as additional cleaning steps, to ensure the quality of their products.\n    <\/p>\n<h2 id=\"contact\">Informaci\u00f3n de contacto<\/h2>\n<p>If you have any questions or need further information about our Factory Supply Phenolphthalein Cas 77 - 09 - 8, please feel free to contact us.<br \/>\n        Correo electr\u00f3nico: info@vivalr.com<br \/>\n        Tel\u00e9fono: (86) 15866781826\n    <\/p>","protected":false},"excerpt":{"rendered":"<p>Factory Supply Phenolphthalein Cas 77 - 09 - 8 With Best Price: User Guide Table of Contents Basic Information and Parameters Product Uses Product Usage Usage Case Studies Contact Information Basic Information and Parameters Phenolphthalein, with the CAS number 77 - 09 - 8, is a widely recognized chemical compound.
