I'm doing a flame testing lab in which I'm supposed to be able to identify an unknown element by observing the color it emits once heated. The color of the flame after heating this unknown metal is a light pinkish-violet. The question I need to answer asks what metal ion this unknown could be. Please help! Am I supposed to use the color spectrum? I don't know how to identify a metal using just its color after being heated and the color spectrum. I appreciate all the help, thanks!
Not many elements can be identified by the flame color. The most common ones are:
Pinkish violet -- K
Very bright yellow orange -- Na
Red -- Li or Sr (different shades of red)
Pale green -- Ba
Bright green -- Cu
Orange -- Ca, Mg, and other elements
Thank you for helping me.
