Answer 1

The gas that is being blown into the bromothymol blue solution, which causes it to turn green, is **carbon dioxide**. When carbon dioxide is added to the solution, it forms carbonic acid, which changes the pH and thus alters the color of the bromothymol blue indicator from blue (in basic conditions) to green (in neutral conditions).

If you have a follow-up question regarding the color of the solution, please provide further details!
