LAB #6 Photosynthesis and Cellular Respiration

Bromothymol blue is yellow under acidic conditions, that is when the pH of the solution is less than 7 (e.g. pH = 6).This occurs when the concentration of CO 2 is high. When there is little or no CO 2 in the solution, the pH will be ~7.6 and the bromothymol blue will actually be blue. Picture the relationship of pH to CO 2 concentration being on a

Chemistry (A-level) - CIE Notes

Bromothymol blue indicator changed from blue to yellow over the range 7.6 to 6.0 where the slope is steepest Due to the sharp change in pH, other indicators can be used which change within this region (e.g. phenolphthalein – pH range 8.2 to 10.0):
