LAB #6 Photosynthesis and Cellular Respiration
www.lamission.eduBromothymol 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

It is okay to add extra deionized water after you record how much Ca(OH) 2(aq) you use. b Record the volume of the Ca(OH) 2(aq) aliquot you use to 0.01 mL. Use either 5.00 mL or 10.00 mL for your trials. You should aim to use about 10 mL of the dilute HCl for each titration.
