Bromothymol blue is an indicator dye that turns yellow in presence of an acid. It remains blue if the pH of the given solution is greater than 7.6 and yellow when the pH is less than 6. The yellow coloration is due to the formation of carbonic acid in the from the carbon dioxide present in the solution.
When aquatic plants are added to two test tubes containing bromothymol blue, stoppered and kept in dark for two days, no color change is observed. It is because the carbon dioxide present is utilized in the process of photosynthesis by plants. If the experiment is conducted in presence if the light, the color of bromothymol blue would be yellow due to the presence of carbon dioxide.

Explanation:
<u>It take for bacteria to form on food - </u>
- Bacteria grow most rapidly in the range of temperatures between 40 °F and 140 °F, doubling in number in as little as 20 minutes.
- This range of temperatures is often called the "Danger Zone." Never leave food out of refrigeration over 2 hours.
How fast do bacteria grow on food?
- When food is in the "danger zone" of temperatures, which is defined as being between 40 and 140 F, the USDA claims that bacteria multiplies every 20 minutes.
- Always put your meals in the refrigerator after two hours if you can help it.
How long does it take for bacteria to produce?
- Bacteria are among the fastest reproducing organisms in the world, doubling every 4 to 20 minutes.
- Some fast-growing bacteria such as pathogenic strains of E.
