What makes a green flame in a flame test?
You may have seen it only briefly but it was there. The green color denotes the presence of the element boron (B) which you’d expect in boric acid. The cream of tartar yielded a purple-colored flame. Purple is associated with the presence of potassium (K).
Which is the best flame test for Science?
The best flame test loops are made from platinum wire but is usually far too expensive for most schools to use. With nichrome flame loops, a trace of orange flame is usually visible when heated in a Bunsen flame. If you take this into account before you test the compounds, it can easily be ignored.
How to do a flame test and interpret results?
How to Do a Flame Test & Interpret Results. The flame test is used to visually determine the identity of an unknown metal or metalloid ion based on the characteristic color the salt turns the flame of a Bunsen burner. The heat of the flame excites the electrons of the metals ions, causing them to emit visible light.
