It depends on the conentration, did a test today with several nitrates (incl. lead nitrate) and they were all yellow/orange...
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.
The color of lithium in the flame test is red.
Lead iodide.
for the metal present. copper is green, sodium is orange, etc.
In a flame test , the sodium ion will produce a bright yellow flame. The nitrate ion does not produce a colour. Dissolve sodium nitrate in water. Then using a ni-chrome wire, clean it in hydrochloric acid, dip the clean wire intoi the solution. Then pass the wire through a bunsen flame. The pale blue flame, will become bright yellow. Different metal ions produce different flame colours. Lithium = red Potassium = lilac Copper = Blue/green
A flame test.
it doesnt change the color of the flame.
red. crimson.
Flame test. Dip a piece of platinum wire into concentrated nitric acid, and then roll it in the sample. Put the wire over a Bunsen flame. If a lilac flame is observed, it is potassium nitrate.
I presume you mean silver nitrate. A flame test detects only the metal ion in a compound. There isn't one for silver.
Blue
Lead iodide (Pb2I) precipitates as a yellow solid, leaving a solution of potassium and nitrate ions.
The colour of any sample containing copper ions burns with a bluish green flame in the flame test.
All sodium salts will give a yellow flame test, because of the metal sodium in the compounds.
The Ignition test is a test for aromaticity. One takes a sample of their unknown, places it in an open flame and observes what happens. The presence of an aromatic ring will usually lead to the production of a sooty yellow flame in the test.
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.
If you have the solid of whatever your testing and you burn it (flame test) it will burn with an orange flame if sodium is present. To establish whether it is sodium CHLORIDE, ad a solution of what your testing to silver nitrate and it should form a white precipitate if it's sodium chloride.
