Lab #2: Unknown Strong Acid Lab/Questions and Concept Test

Go to lab page: https://chemcollective.org/acid-base

Points Possible: 15  Instructions for Virtual Lab: Record all observations and take screenshots of your work

Replacement lab: Determine the Concentration of the Unknown Strong Acid and Concept Test

· Strong Acid

  1. Determine the Concentration of the Unknown Strong Acid          
  2. 3 Lab Questions dealing with the Acid Lab (found below)
  3. Concept Test (note you will need to write the answers down separately)

+5 Screen Shots Lab and correct page, answers to both the 3 lab questions and concept test.

Click on the words "Unknown Acid Problem" (on the right side just above Work Bench 1) which will further explain the lab problem within this assignment.

The Lab will center on:

  • Determining the concentration of the Acid (showing math steps and auto graded answer).
  • 3 Lab Questions
    • 1.  Briefly describe the equivalence point in a titration. What species are present?
    • 2. Phenolphthalein is an indicator that will change color at pH close to 8. Why would we use phenolphthalein to determine when the equivalence point is reached?
    • 3. At what point do you know that you have added enough base from the buret into the acid solution? What happens to your calculations for the concentration of the acid if you accidentally add in more base than you need to?
  • Concept Test (note you will need to write the answers down separately)
