In forensics, the dermal nitrate test detects the presence of unburned gunpowder and nitrate residue on the hands of a suspect.
The brown ring test allows you to see if nitrate is present in a soloution. I nitrate is present then a brown ring will form around the testube.
this is because nitrate reductase test using the production of nitrite from nitrate as a measure of nitrate reductase activity
Povidone-iodine may elevate test results for bilirubin, uric acid, phosphorus, and potassium, and therefore is not recommended for use with dermal puncture
It measures in patas
Enterobacteriaceae are nitrate +. Don't know about Pseudomonas, though.

A common test for nitrate ion is with diphenylamine.
S. aureus is Nitrate Reduction test positive....

It depends on the conentration, did a test today with several nitrates (incl. lead nitrate) and they were all yellow/orange...
red. crimson.
no
I presume you mean silver nitrate. A flame test detects only the metal ion in a compound. There isn't one for silver.
