A titration of 25.00 mL of an unknown HCl solution with 0.1240 M NaOH starts at a buret reading for NaOH of 0.53 mL. The phenolphthalein indicator turns light pink in the acid solution for over 30 seconds at a buret reading of 27.30 mL. 5. What was the volume of NaOH dispensed? 6. How many moles of NaOH were dispensed? 7. Write the balanced molecular equation for the neutralization reaction: 8. How many moles of HCl are present in the acid solution? 9. What is the molarity of the unknown HCl solution?
