The mendelic acid "chemical face peel" is a relatively new innovation for the rejuvenation of problem skin. In addition to removing dead skin cells, its antibacterial properties help acne-prone skin. The technique has also been touted as a way to improve hyperpigmentation due to post acne scarring. Although the compound was first derived from bitter almonds, mendelic acid is generally now synthesized in the laboratory. To formulate one of these "face peel" emulsions, you are asked to prepare as much pH = 3.799 buffer solution as you can from 100.00 mL of 0.5000 M mendelic acid (HMend). Since the use of mendelic acid is relatively new, the conjugate base mendolate (Mend') cannot be purchased. Fortunately, you have plenty of 0.4087 M NaOH. Ka = 3.894x10-4 for mendelic acid. How would you prepare the buffer solution? The following questions will guide you to find the final answer. What is the moles ratio between the equilibrium molarity of mendelic acid (MA) and mendolate? Please provider your answer below. A. B. C. Please provider your answer below. How many moles of mendolate in the buffer solution? 0² - → S + A moles How many mL of NaOH solution is needed? The reaction between mendelic acid (MA) and NaOH is HMed + NaOH →NaMed + H₂O mL
