A positive PDase test will result in what color change in the media when the appropriate reagent is added? If fermentation occurs in the phenol-red carbohydrate fermentation broth the media will turn what color?
Case #2 • A newborn infant develops severe vomiting and symptoms of metabolic acidosis. • Results of UA are: Positive for ketones and negative for glucose and other reducing substances • Questions: 1. State a UA screening test that would be a positive in this patient? 2- if the urine had an odor of "sweaty feet", what metabolic disorder would be suspected? Case study #2 • 3-State an additional UA screening test that might be ordered on the infant. If...

Why does 0.01M KMnO4 not change color at first when it is added to 0.025M of Na2C2O4 (sodium oxalate)? I did a titration of KMnO4 and Na2C2O4 a week ago and initially when I added the KMnO4, it turned the sodium oxalate a deep purple. It later turned colorless after about 15 seconds. Why is that? Is there a reasonable explanation?
please help me write mechanism of this reaction and explain why I observed the bromine dissolved in dichloromethane when added to the alkene the solution changed to light yellow. 3. Write a chemical equation for the test for unsaturation (Part B) using one of the possible alkenes above. What observation is made for a positive test and why? Explais Brz CH,CeZ The bromine dissolved in dichloromothane added to the alkene changed to light yellow, indicated a Postive resut
C. Bromine Test for Unsaturation 2. Saturated/Unsaturated 1. Color fades rapidly/persists Fatty acids Stearic acid Oleic acid Triacylglycerols Safflower oil Olive oil Questions and Problems Q3 a. Draw the condensed structural formulas of stearic acid and oleic acid. Stearic acid Oleic acid b. From the results of Part C, which is more unsaturated: oleic acid or stearic a Explain your reason. From the results of Part C, were safflower oil and olive oil saturated or un rated? Explain your reason.
I did the litmus milk test for my microbiology lab. My results came back as a no color change in the litmus milk sample, but when my sample was tilted it did shift. What are my results from this experiment? my sample is sample d. I'm trying to write a lab report, but I don't know what to write. I can't redo this experiment. b d.
ELISA-HIV Testing DATA SHEET RESULTS For each of the following, report the color and indicate whether the result was positive or negative. Neg.control: negative Donorl: negative Pos. control: positive Donor 2: positive Based on your results, which donor has been exposed to HIV? Donor 2 QUESTIONS 1 Describe the purpose of the two controls. The purpose of the two controls is to show what the positive and negative would look like, and it also helps determine it the experiment was...
yellow, green or red, the test is positive. The color of the solution depends on the concentration of 3. Observe the color of your negative and positive controls. Note which one has a red color. 4 After the dialysis of the NaCi-elucose-red dye solution has progressed for an hour, test the water outside the dialysis bag (your experimental data) for the presence of Ci and glucose same way you did for your controls in steps 1 and 2. Observe if...
