Iridium is a silvery-white metal.
I think sorry if im wrong but it's BLACKISH
with a hint of purple in it
Barium ions give off a green colour when heated in a flame.
well , the colour of potassium chloride is a lilac colour :) hope this helps
With a shiny blue flame.
its a orange colour when closed and a blue colour when is open
The flame color of barium burning in oxygen is green.
It is silvery white in colour
When sodium oxide is burned, it typically produces a yellow flame.
The colour turns brick Red .
You turn the air admittance ring at the base of the Bunsen burner until it is fully open. this allows the hottest flame to be produced and has a blue colour
Chlorine gas itself does not emit a colored flame when subjected to a flame test. Instead, it will impart a green color to the flame when a sample containing chlorine (such as a chloride compound) is included in the flame test.
You get and orange - yellow colour.
I suppose that the flame test was not applied to californium.
The blue flame.
Limitations:The nichrome wire may still have impurities after cleaning in the hydrochloric acid. This may have an affect on the colour of the flame. This in turn will have an affect on the results obtained, having an affect on the whole experiment.Another limitation is that the flame already burns red/orange so this may make it a judgement call of what colour the flame is. If this judgement is incorrect the results of the experiment will be affected.The test cannot differentiate between all elements. Several metals produce the same flame colour. Some compounds do not change the colour of the flame at all.Sodium is present in most compounds and will colour the flame. Sometimes a blue glass is used to filter out the yellow of sodium.The test cannot detect low concentrations of most ions.
Blue?
yellow
