When heated the electrons move from the ground state to an exicited state. They are unstable here and return to the ground state giving off energy in the form of a specific color. Different energy levels will produce different colors

Flame colour depends on what elements are present in what you are burning. Here are a few common elements and the flame colour that appears when you burn them:
barium = light green
calcium = brick red
copper = blue/green
lead = blue/white
potassium = lilac
sodium = bright orange
lithium = red
rubidium = red/violet
cesium = blue/violet
strontium = strong red
Hope this helps you a little bit with your lab report.

you may want to do one the position you've 5 different ideas of different salts. you comprehend what salts there are, yet you dont comprehend which one is which. then you definitely proceed to % out each and each and every by technique of blending them with different chemical substances and observing the formation of precipitates/colors and then use deductive reasoning to % out all of them.
