Lab # 2: Strong Acid

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

Purposes:  Determine the Concentration of the Unknown Strong Acid and Concept Test

  1. Strong Acid
    1. Determine the concentration of the unknown strong acid          
    2. 3 lab questions dealing with the Acid Lab (below)
      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?
    3. Concept test (note: you will need to record the answers separately)

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:
