6 CO2 + 12 H2O - - -> C6H12O6 + 6 O2 + 6 H2O
Carbon dioxide forms carbonic acid in water: CO2 + H2O - - -> H2CO3
NOTE: wear goggles; exhale only, do not inhale (drink)!
60 minutes exposure.
NOTE: Use enough of the Phenol Red (about 10 ml) to completely cover the leaves.
Also make sure the tops are securely screwed tight, so that no CO2 from the atmosphere leaks into your tubes.
Please save the Cabomba pieces; we can regrow them for later use.
OPTIONAL (unless there is enough Cabomba to perform this experiment at the same time as PART A).
