State lactic acid and assume that the solid was dissolved

Reference no: EM13181576

Part A:

How many milliliters of 0.100 M NaOH are required to react completely with a sample of the solid carboxylic acid lactic acid, CH3CH(OH)COOH, with a mass of 0.1351 g (molar mass of lactic acid is 90.08 g/mol) The acid is monoprotic, only the last H dissociates.

Part B:

what is the pH of the resulting solution after the nuetralization reaction (that is after the required amount of NaOH is added to the lactic acid)? Use a Ka of .00014 for lactic acid and assume that the solid was dissolved in 15.0 mL of distilled water to prepare for titration.

All work needs to be shown. I know part B needs the henderson hasselbalch equation.
