Question
What is the purpose of the vial that does not contain chara?
(the solution with chara turned green showing that it is neutral)
(the btb solution was yellow so it was acidic)
Transcribed Image Text:Background and Procedure:
The chemical bromothymol blue is an indicator that appears blue in an alkaline (base) medium and yellow-
green in an acid medium. CO2 has been added to the bromothymol blue. Carbon dioxide (CO2) in solution forms
carbonic acid (H2CO3), turning the bromothymol yellow-green.
If carbon dioxide is removed from the solution, the solution will change to dark green and then to blue.
Bromothymol blue will stain your hands and clothing. Practice safe laboratory procedures when performing this
activity.
1. With a permanent marker, write your initials (or group symbol) on both of the capped vials.
2. Obtain an 8-cm sprig of Chara and place it in one of the vials provided.
3. Over a paper towel, fill both vials to overflowing with the yellow-green bromothymol blue solution and cap
tightly. Take care not to spill on your hands and thoroughly clean up any spills.
4. Place both vials in sunlight or strong light source.
5. Wait one hour, and then answer the questions for Activity 1.
