After carbon dioxide was blown into the test tube, what color was the bromothymol blue solution?
Yellow
-
Why did the color change yellow after the carbon dioxide was blown into the solution?
The solution became acidic due to the production of carbonic acid.
-
As photosynthesis occurred, the color changed to ____ because
blue; carbon dioxide was being used by the plant for photosynthesis so the environment was becoming more alkaline
