You exhale CO2 which is produced during cellular respiration. CO2 combines with the water in your blood's plasma to make up one half of the body's most important buffer pair, carbonic acid. The more physical activity you engage in, the more CO2 your body is producing. You can see this by putting some of the cabbage indicator in a glass and then blowing bubbles into it through a straw. Can you see a change in the color of the indicator?

Answer:

Yes, there is change in the color of the indicator.

Explanation:

Cabbage indiccator is a purple/blue solution that will change color with the change in pH.

A more acid substance will turn the indicator red and a more basic substance will turn the indicator green.

The bubbles are made of CO₂, which will react with the water in the indicator solution to form carbonic acid. Since the solution will turn more acidic, the indicator will change from a purple color to a red color.
