Photosynthesis lab: elodea and carbon dioxide in this lab titled the elodea took my breath away students will be able to see photosynthesis in action as colors change (or don't) using elodea, bromothymol blue, and carbon dioxide . My lab group made up a lab in biology we put 1 elodea plant in each graduated cylinder and poured in some bromothymol blue we plugged the cylinders with stoppers and waited 48 hours to see the difference in bromothymol blue. A final cylinder containing an elodea plant bromothymol blue and water should have been prepared before this activity and left in a dark place for 24 hours [no change will occur because sunlight is required for photosynthesis to occur].
This lab uses the chemical bromothymol blue this chemical is used as a ph indicator when the ph is above a 7 (basic) it is blue, but when the ph drops below 7 (acidic) it starts to turn yellow. Regular photosynthesis lab - elodea & bromothymol blue elodea plant, the chemical bromothymol blue (which acts as an indicator to show if photosynthesis is . Lab: investigating photosynthesis and cellular respiration background: if i add a snail and elodea to a test tube with bromothymol blue, then the water will turn .

Bromothymol blue elodea lab
Bromothymol blue solution elodealabpaq t1 – t0 bromothymol blue solution in foil 5mins average of other students’ results: total time for color changeexperiment photosynthesis and respiration data table 4: observation of ph change in the oxygen cycle contents of respirometer initial color t0. Water plus bromothymol blue plus elodea (an aquarium plant) is blue-green in light water plus bromothymol blue plus a snail plus elodea is blue-green in light and yellow when left in the dark for three hours. In light: water combined with bromothymol blue with the addition of a snail and elodea results in a blue-green color in light because the plant photosynthesizes in dark: water combined with bromothymol blue plus a snail and elodea results in a yellow solution in the dark because there is no light therefor the plant has no light for photosynthesis. Bio lab: bromothymol blue jiyong the photosynthesis lab had some elements of inquiry— elodea in blue or yellow btb in light.
- Purpose: to observe the effect of elodea on carbon dioxide in water under various conditions background: this experiment uses the acid base indicator bromothymol blue it is used to measure tiny changes around the neutral ph (7.
- Lab 5: photosynthesis photosynthesis lab 5 data table in the question section of this lab note: bromothymol blue turns blue to elodea plant you may need to .
- Elodea and bromothymol blue photosynthesis is the process by which plants take carbon dioxide from the atmosphere, add water, and use the energy of sunlight to produce sugar write the equation for photosynthesis:.
As a result, an acid-base indicator such as bromothymol blue can be used to indicate the presence of carbon dioxide in this laboratory investigation, you will use bromthymol blue to explore the relationship between photosynthesis and respiration. Water plus bromothymol blue plus a snail plus elodea is blue-green in light and yellow when left in the dark for three hours analysis and conclusions: water plus bromothymol blue is blue-green because the water is a natural ph leaving the color as blue green. Bromothymol blue color change photosynthesis and respiration lab what happened in the test tube with the snail and the elodea. Photosynthesis and cellular respiration are two we will be using the same plant you examined in lab 3 called elodea the ph indicator bromothymol blue is used .
