Bromthymol Blues Lab

Bromthymol Blues Lab Introduction In this lab our stem will manifest if atomic number 6 paper dioxide ( carbon dioxide) is kick in during photosynthesis and cellular respiration. We will attempt this investigate by employ an exponent called bromthymol blue. This indicator will rhythm yellow if carbonic acid gas is present during cellular respiration and during photosynthesis the indicator will debase from yellow to blue if the CO2 has been imprisoned by the plant. II. affair To demonstrate that CO2 is used during photosynthesis. To demonstrate that CO2 is produced during cellular respiration. III. Hypothesis 1. If we put elodea, bromthymol blue, tonic wet, and mending piss in a phial in the sunlight then we put up demonstrate that carbon dioxide is used during photosynthesis because the indicator will sour blue. 2. If we put elodea, bromthymol blue, and regular water in a phial in the dark then we can demonstrate that carbon dioxi de is produced during cellular respiration. IV. Materials 1. Bromthymol blue 2. Capped vials (Gerber baby food jars) 3. genus Elodea (aquarium plant) 4. Light and dark areas. V. Procedures 1.Divide into a group of 4 2.
