Consider a titration where 0.215 M potassium hydroxide is added from a burette to 10.00 mL of hydrochloric acid in an Erlenmeyer flask under the burette. A few drops of phenolphthalein are added to the acid in the Erlenmeyer flask. The burette used in this titration is initially filled with potassium hydroxide to the 4.48 mL mark and ends at the 27.73 mL mark once the titration is complete. What is the concentration of the original hydrochloric acid solution?
