Phenol red, a pH indicator, is used in the experiment to determine respiration activity by showing CO2 production.

Table: CO2 Production by Beans
Beans	Indicator Color (Phenol Red)	Conclusion (CO2 present or absent)
Germinating	Yellow	Present
Ungerminated-dry	Red	Absent

Questions;

1. How does phenol red work as a pH indicator?

2. Why does this show respiration activity?

Mix the watery environment of Elodea with a pH indicator called phenol red. In the presence of an acid, phenol red will appear yellow. In the presence of a strong base, phenol red will appear purple. Intermediate colors correspond with intermediate pH values. Recall that plants use CO2 for photosynthesis; the concentration of CO2 will determine the pH of a solution. Plants also produce CO2 as a byproduct of cellular respiration. Will a solution with a high concentration of CO2...

Phenolphhalein indicator is used in this experiment because it changes color in the pH range of 8.0 to 9.6. Show by calculation that phenolphthalein is an acceptable indicator for the titration of KHP with NaOH. This is true if the pH at the equivalence point falls within this range. In essence, what you need to do is to calculate the pH of the unprotonated phthalate salt. You may assume that the concentration of the salt is approximately 0.05 M at...

What can cause a phenol red indicator of carbohydrate fermentation to give a false positive with...

What can cause a phenol red indicator of carbohydrate fermentation to give a false positive with gas? I heavily incubated my organism in the test tube and it is producing a huge gas bubble in the Durham tube and a clear yellow (acid) color. I incubated my tube at my organism's optimism growth conditions (oxygen and temperature wise) for 48 hrs exactly.. i was supposed to get a red no gas result ( -) what might have gone wrong?

The anthocyanin in hydrangeas can be isolated and used as an environmentally friendly pH indicator for titrations. At the end of a titration reaction of a strong acid with a strong base, you have a neutral solution. What color do you expect anthocyanin to be at the end of a titration? Describe a lab experiment to support your prediction.

2. An experiment was conducted to determine if a drug could be used as a treatment for the eating disorder anorexia. The test subjects were women being treated for anorexia. A group of 50 patients received the drug, and after a year, 39 were deemed healthy. Construct a 99% conﬁdence interval for the true proportion of patients who would be deemed healthy after receiving the drug for a year.

The photogates in the experiment are used to determine the speed of the gliders passing through. The photogates measure the time it takes for the photogate beam to go from being unblocked to blocked to unblocked again. You tell the photogate how long your glider is, and the speed is then calculated. Given the description of what the photogates do, how will you determine the velocity of the glider?
