Explanation:
The flame test is an analytical method used in chemistry to detect the presence of certain elements, mainly metal ions, based on the characteristic emission spectrum of each element. The color of the flame can also depend on temperature, identify the unknown element or simply a metallic ion based on its characteristics when emitting light.
Have a nice day!
