Copper (II) Nitrate burns in a Green flame
Copper nitrate is definitely a blue colour, even though copper (II) ions, Cu2+, generally produce blue-green solids and solutions.
Its colour is dark blue just like that of copper sulphate.
May be bluish-green
Copper ions flame test blue-green.
The colour of any sample containing copper ions burns with a bluish green flame in the flame test.
The nitrate ion is the oxidizing agent in the compound without it you could not burn the chemicals and you could not produce a spectrum so there would be no emission of color
Sodium nitrate itself does not burn. It is an oxidizer. It can be used in place of oxygen to burn materials.
A: If you put a piece of copper wire on any type of flame (most preferably cooking flames), then you would observe that they produce a green color in the flame. Sometimes, it might give youa blue tinge but if it doesn't, it doesn't mean that there's something wrong with the copper you're using.
Silver is slightly more reactive than gold, although they are both very unreactive. Assuming that the gold nitrate exists, because it would be very rare, silver would react with it and displace it. The products formed will be silver nitrate and gold.

The color of lithium in the flame test is red.

Silver nitrate doesn't burn.
The color is due to the radiation emitted by copper.
Sodium nitrate itself does not burn. It is an oxidizer. It can be used in place of oxygen to burn materials.
The chemical change causes the color change when the two new chemicals combine.
Strontium nitrate emits a bright red flame when it is burned.
If you burn Rubidium Nitrate, it will be violet-red. Strontium Nitrate will burn as a very bright, distinct red. Both of these chemicals are used in making fireworks these colors. Hope this helps!
