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?

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?

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.
