When testing microaerophils some microbiologists prefer to use a semisolid nitrate medium that contains a small amount of agar why is this done?
Microbiologists testing microaerophils prefer to use a semisolid nitrate medium that contains a small amount of agar to get more accurate results. This is also done to speed up the results.
Is klebsiella pneumoniae positive for nitrate testing?
Yes, almost Enterobacteriae are positive for nitrate reduction.
What is the positive color of silver nitrate?
When testing silver nitrate, a whitish color will yield positive results. If the test is negative, the color will turn clear and it will remain transparent.
Where can one find information about Sibling DNA Testing?
Someone can find information about Sibling DNA testing from a number of websites such as Gene Track Canada. The website contains extensive information about sibling DNA testing and also provides locations where individuals can go to get sibling DNA testing done.
Is there any agency here in the Philippines that can do DNA testing?
There is paternity testing and DNA testing in the Philippines. It can also be completed at the United States embassy.

Silver nitrate is used for testing of which chemicals?
Iodide

What does simple nutrients mean?
Simple nutrients is a term used in water testing. The test looks for Ammonium, Nitrate Nitrate plus Nitrite, and Phosphate in your water sample. There is an MSDS standard quality that should be met.
What effect does the nitrate ion have on the color of the flames?
None. Using flame spectral analysis, we can use a prism or other device to determine the color of various metals. Nitrate gives no color. The purpose of the test is to give metal detection, qualitatively. Testing for nitrate is another test, not involving flame.
What tube color to use for collection of blood for electrolyte testing?
Green tube which contains the anticoagulant Heparin is ideal for electrolyte testing.
Why add dilute nitric acid with silver nitrate to test for halide ions?
The nitric acid reacts with other ions that might precipitate with silver nitrate. Doing this first gets these other unwanted precipitates out of the way. If you are testing with Fluoride as your halide remember that silver nitrate does not precipitate with Fluoride, so no precipitate does not mean that halide ions are not present.

What is ring test?
it is also know as brown ring test. it is a nitrate test to determine the presence of nitrate ion in the solution Testing for the presence of nitrate via wet chemistry is generally difficult compared with testing for other anions, as almost all nitrates are soluble in water. In contrast, many common ions give insoluble salts, e.g. halides precipitate with silver, and sulfates precipitate with barium.The nitrate anion is an oxidizer, and many tests for the nitrate anion are based on this property. Unfortunately, other oxidants present in the analyte may interfere and give erroneous results.Brown ring testA common nitrate test, known as the brown ring test can be performed by adding iron(II) sulfate to a solution of a nitrate, then slowly adding concentrated sulfuric acid such that the sulfuric acid forms a layer above the aqueous solution. A brown ring will form at the juction of the two layers, indicating the presence of the nitrate ion. Note that the presence of nitrite ions will interfere with this test.The overall reaction is the reductionof the nitrate ion by iron(II) which is oxidised to iron(III) and formation of a nitrosyl complex.NO3- + 3Fe2+ + 4H+→ 3Fe3+ + NO + 2H2O [Fe(H2O)6]2+ + NO → [Fe(H2O)5(NO)]2+
Which Technical Service Bulletin contains field-testing specifications for UTP Cat 5 cabling?
TSB-67
How do you find out how healthy your aquifer is?
You can find out how healthy your aquifer is by testing the water for microbes. If the water contains microbes, boil it before drinking it.
