In this activity you will use the virtual lab to determine the concentration of a strong monoprotic acid. To do this, you can perform a titration using NaOH and phenolphthalein found in the virtual lab. (Note: The concentration of the acid is between 0.025M and 2.5M so you will need to dilute the NaOH solution so that the volume to reach the endpoint is between 10 and 50 mL). Once you have determined the concentration of the acid, please enter your answer into a form at the bottom of this page.

Follow-up Question
For this virtual lab you will have to determine the concentration of a strong monoprotic acid. You will first have to dilute the 10 M sodium hydroxide solution, as your acid will have a concentration between 0.25 M and 2.5 M. You have to use between 10 mL and 50 mL of your diluted sodium hydroxide solution during the titration.
