What is the molecular formula of the compound? Molar Mass: 318.3228. :: Chemistry Applications:: Chemical Elements, Periodic Table. The phenolphthalein indicator has a range from 8.2 - 10 in a solution. The buret contains 0.270 M NaOH. Doesn't work well for trial 1, 2, 4, 5 because all their equivalence points are below 8.2 - 10 pH threshold. The molar mass of phenolphthalein is 318.31 g/mol. The number of moles of diprotic acid in the flask is half the number of moles of NaOH you need to …
What is this information? The flask shown here contains 0.446 g of acid and a few drops of phenolphthalein indicator dissolved in water. EXPERIMENT 7: ACID-BASE TITRATION: STANDARDIZATION 91 Standardizing the NaOH Solution In the lab notebook, set up a data table similar to the one given at the end of this exercise. Your instructor will indicate which procedure you are to follow (Part I or Part II). EC Number: 201-004-7 CAS #: 77-09-8 Grade: ACS,Reag. Version # 3.0 Prepared by This SDS has been prepared by SUEZ Regulatory Department (1-215-355-3300). Phenolphthalein is a chemical compound with the formula C 20 H 14 O 4 and is often written as "HIn" or "phph" in shorthand notation.Phenolphthalein is often used as an indicator in acid–base titrations.For this application, it turns colorless in acidic solutions and pink in basic solutions. Moles to Grams Calculator. Standard Phenolphthalein Solution: Dilute one mL of a phenolphthalein solution with 4 mL of ethyl alcohol. Since molar mass has units of grams per mole, you can calculate the molar mass of a sample by dividing its mass in grams by the number of moles in that sample. The molar mass of KHP is 204.2 g/mol Expert Answer However, phenolphthalein is no longer used as a laxative due to the suspected carcinogenicity of this compound.
