What happens over time if you put a plant bromothymol blue?

Bromothymol blue is a pH indicator that changes color based on acidity or alkalinity. When added to a plant, it can help visualize changes in pH in the surrounding soil or water. Over time, if the plant undergoes photosynthesis, it will take in carbon dioxide and release oxygen, which can affect the pH and thus the color of bromothymol blue. If the environment becomes more alkaline due to oxygen production, the solution may change from yellow to blue, indicating a shift in pH.
