Flame tests | Causes of Color
Flame Color tells us about the temperature of a candle flame. The inner core of the candle flame is light blue, with a temperature of around 1670 K (1400 C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange, and finally red.
Q & A: Flame test: ion or anion? | Department of …
If you use a pure metal powder and observe a color spectrum, it is clearly due to the metal atoms as there is nothing else. The question that you are asking comes into play when you use a metallic salt, which upon heating disassociates into metal ions and nonmetalic anion atoms or groups.
