Bromothymol blue solution is used as an indicator to determine the rough pH of a substance. It is prepared from a powder, household items and common laboratory chemicals that can be obtained through a scientific supply house individually or as a kit. The mixed bromothymol blue solution will turn...
4. Explain how the bag is a model for the cell. 5. Sketch the cup and baggie in the space below. Use arrows to illustrate how diffusion occurred in this lab. 6. What would happen if you did an experiment in which the iodine solution was placed in the baggie, and the starch solution...
Why is bromothymol blue a good indicator with which to test all solutions first? What color change would get when one drop of BTB to H_3PO_3. How can the Tyndall effect be used to distinguish between a colloid and a solution? Can the presence of Brownian motion distinguish...
25cm3 of the K solution was pipetted in a 250cm3 beaker and a few drops of dilute NaOH and bromothymol blue indicator added to it. Any precipate formed at that point was then filtered off. 5% ethanoic acid was added until the colour of the solution changed to yellow. The solution was...
The color change of the bromothymol blue with water is caused by carbon dioxide from your breath. How can you test this hypothesis? Define hypoxia. How does pH affect the chemical form of a toxicant in water? Explain how atmospheric nitrogen dioxide (NO2) decreases the pH of water in cloud...
Why is bromothymol blue a good indicator for titration? How do decantation and filtration differ? How should a microscope be carried? (a) Why is being able to measure density precisely a useful tool in Biology? In the first paragraph describe how you could measu...
Explain what a flame test has to do with spectroscopy. Why is bromothymol blue a good indicator with which to test all solutions first? When heating chemicals that could be volatile, what would be the best way to conduct this experiment? Explain how a mass spectrometer works. Why would ...
