You perform an uknown nitrate test.............?

All nitrates are soluble.  You would need to consult a table of solubilities to see what other ions you could use to precipitate out the cations.\n\nEx:  If you had silver nitrate in a solution you could add something with a halide ion such as sodium chloride.  The silver ion would precipitate out with the chloride ion.  If no ppt forms with the sodium chloride you know it was not silver ions.\n\nThen look for other ions that you could test for.

Yes, have a good test

are you sure you are not on something stronger than oxygen?

The nitrogen gas in air gets converted to 1) ammonia 2) nitrates (from nitrites)

Since you didn't say what results you desire it is not really possible for anyone to answer your question.\n\nBut KNO3, potassium nitrate, commonly called "salt peter", is an oxidizing agent used in gun powder.  It can also be used as a fertilizer.  It is also a diuretic, although a poor one and humans should not use it.

too many nitrates is not good, because then you get a ton of algae growth and the algae uses up all of the oxygen causing the other organisms to die\ndont know bout the other question

Choice C: bacteria change N2 gas into nitrates and ammonia so that plants can use that necessary chemical.

The nitrate ion is a good oxidizer, meaning it is reduced and the other species it reacts with is oxidized. The flame test is color dependent on the oxidation state (or number of electrons) present in the metal you are analyzing. So I would imagine that if you were analyzing something like the copper (I) cation in the flame, the color would change due to the fact that the nitrate ion is causing another oxidized copper species to be produced, such as copper (II), which has a blue color. Hope this helps and let me know if you have any other questions!

!st, and most important use of nitrogen is what you are doing right now. It's mixed with the oxygen which you & I are breathing.

you should go have another test done

what foregin substance are you talking about first...

Experiment w/ what works for you.

Not sure, but practice before taking it.

Probably a t-test. \n\nTell us what hypothesis you are testing.

What do you need to know?  Nitrous

Don't know try it and tell us.  \n\nWould you sniff this?\n\nhttp://plaza.ufl.edu/kbeaz/severe_calculus.jpg
