Iron nitrate typically produces a yellow-orange flame color when it is heated. This color is due to the presence of iron ions in the compound.
Silver nitrate does not produce a flame color on its own. When silver nitrate is burned, it decomposes into silver metal, nitrogen dioxide gas, and oxygen, but it does not emit a characteristic flame color.
Copper II nitrate typically produces a blue-green flame when burned.
The flame color of sodium nitrate solution is a bright yellow color. When the solution is heated, the sodium ions emit this characteristic yellow color when they are excited and then return to their ground state.
Potassium nitrate typically produces a purple flame when burned.
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 flame of strontium nitrate is red. It produces a bright red color when ignited.
Lead compounds tend to be blue in flame tests
Cupric nitrate typically produces a blue-green flame when burned.
Selenium nitrate typically gives a pink or reddish flame color when subjected to a flame test.
The flame of barium nitrate typically produces a pale green color when burned. This green color is a characteristic flame test color for barium compounds.
Aluminum nitrate does not produce a specific flame color when burned. The flame color produced by a compound is typically due to the metal ion present, rather than the nitrate anion. Aluminum itself does not produce a significant color in flames.
Silver nitrate does not produce a flame color on its own. When silver nitrate is burned, it decomposes into silver metal, nitrogen dioxide gas, and oxygen, but it does not emit a characteristic flame color.
Copper II nitrate typically produces a blue-green flame when burned.
I presume you mean silver nitrate. A flame test detects only the metal ion in a compound. There isn't one for silver.
The yellow color of the flame is due only to sodium.
The color of the flame depends on the metal from the salt.
All sodium salts will give a yellow flame test, because of the metal sodium in the compounds.
