Question 20 You are performing a titration of an unknown HCl solution. You want to determine the concentration of this unknown. You place 15.0 mL of the unknown in an Erlenmeyer flask. You add one drop of phenolphthalein indicator. You set up a buret with 0.500 M KOH solution. You start adding the KOH to the unknown acid. After adding 41.5 mL of KOH titrant, the unknown solution turns pink. What is the concentration of your unknown HCI solution in units of Molarity (moles/L)? A) 0.367 M HCI В) 1.53 М НОI C) 1.38 М НСІ D) 0.0208 M HCI E) 2.07 M HCI F) 0.758 M HCI
