I need help with number 2
12. In a titration of HNO3, you add a few drops of phenolphthalein indicator to 50.00 L if acid in a flask. You quickly add 20.00 mL of 0.0502 M NaOH but overshoot the endpoint, turning the solution a deep pink color. Instead of starting over you add an additional 30.00 mL of the acid, turning the solution colorless. It then takes 3.22 mL of the NaOH to reach the endpoint. a. Write the Molecular, Total Ionic, and Net Ionic Equations for this reaction. b. What is the concentration of the HNO3 solution? c. How many moles of NaOH were in excess after the first addition?
