A rock covered with green spots is placed on a screen in a test tube above some bromothymol blue solution; after several hours, the solution remains blue. What can you conclude form this experiment?
AFter doing research, I found out that bromothymol solution is a blue liquid and is an indicator of pH levels and shows if the organism is respiring or not.
So if it's blue, it is not respiring and basic
If the solution is yellow or green, the solution is acidic and the rock is producing CO2.
Why is that in my question at top, the solution stay the same. Why didn't the green spots have any effect?
