Dec 17, 2014 · Bromothymol Blue (BTB) is a blue-green liquid which changes to a yellow color in acid and back to blue-green when returned to a neutral pH. Carbon dioxide plus water yields sugar and oxygen when chlorophyll and sunlight are present. Animals respire. Green plants photosynthesize in the light and respire all the time.

Cellular respiration and exercise are related. As your activity increases, the speed of cellular respiration also increases to keep up with the body's demands.
Phenol red indicator changes from yellow to red over the pH range 6.8–8.4. Thymolphthalein (the alternative bromothymol blue could also be used) changes from blue (alkaline) to colourless (acid) over the pH range 9.3–10.5. See CLEAPSS Recipe Book RB000, which also covers bicarbonate indicator solution.
We noticed the test tubes that had elodea and in the direct light, the bromothymol blue changed from yellow to blue because the elodea was using the carbon dioxide to go through photosynthesis. The test tube that was wrapped in foil and no light could travel to the plant, the bromothymol blue stayed the yellow color because it was unable to go ...

Photosynthesis is the process during which a plant’s chlorophyll traps light energy and sugars are produced. In plants, photosynthesis occurs only in cells with chloroplasts. The chemical reaction for photosynthesis is: 6CO. 2 + 6H 2 O + light energy C 6 H 12 O 6 + 6O. 2 Carbon dioxide Water glucose oxygen Bromothymol blue indicator can indicate the presence of carbonic acid. When little or no carbonic acid is present bromothymol blue will show a blue color. Depending on the amount of carbon dioxide that is added to the solution, bromothymol blue will change to green or yellow. The more yellow the color the greater the concentration of carbonic acid.
