Carbon dioxide production can be measured by breathing through a straw into a solution of bromothymol blue (BTB). Description: Hydrogen carbonate indicator is very sensitive to changes in pH and gives a broad colour change from yellow to purple as the pH changes from 7.6 to 9.2. As you hopefully know, photosynthesis can only occur in the light, as light-dependent reactions require energy gained from photons. We can examine the impact each of these has on photosynthesis, as well as gain more information on photosynthesis as a whole by performing experiments within the lab. Maybe just buy another one in.

Carbon dioxide, which is mildly acidic, is a waste product of the processing (metabolism) of oxygen and nutrients (which all cells need) and, as such, is constantly produced by cells. If you immerse pondweed in a solution containing carbon dioxide, it will gradually deplete the carbon dioxide from the solution unless the carbon dioxide removed during photosynthesis is replaced somehow. One of the easiest practicals to investigate photosynthesis and the effect of varying limiting factors on the rate of photosynthesis is using Cabomba or Elodea plants, more commonly known as pondweed, within a boiling water tube. Phenolphthalein is used as an indicator in acid-base titration because it . By altering the level of carbon dioxide available to the plant, and controlling the temperature and light intensity it is exposed to, we can investigate the impact of different carbon dioxide concentrations on the rate of photosynthesis.
