Why can chemicals produce different colors of fire?

Hypothesis
Hypothesis

What we expected to see was the change in the color of fire.

MaterialsMaterials

* Bamboo Skewers
* Chemicals:
* Copper Sulfate
* Boric acid
* Sodium Chloride
* Masking tape
* Matches
* Heat Resistant Bowl
* Clinic Alcohol
*Containers

Procedure
Procedure

Our experiment consists on having 3 different containers each one with a different chemical (copper sulfate, boric acid, sodium chloride) and we added clinic alcohol toeach container and then set fire to each, and finally we just saw the different colors of fire produced by the different chemical reactions.

Data
Data

* Atoms: basic unit of matter.
*Protons: The proton is a subatomic particle with the symbol p or p+ and a positive electric charge of 1.
* Neutrons: The neutron is a subatomic hadron particle which has the symbol n or n0, no netelectric charge and a mass slightly larger than that of a proton.
* Electrons: The electron (symbol: e−) is a subatomic particle with a negative elementary electric charge.
* Ions: An ion is anatom or molecule in which the total number of electrons is not equal to the total number of protons, giving the atom a net positive or negative charge.
* Photons: A photon is an elementaryparticle, the quantum of light and all other forms of electromagnetic radiation.
* Spectral lines: A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resultingfrom a deficiency or excess of photons in a narrow frequency range.

This experiment could be really useful in real life; rainbow fires are used ascodes to disguise military projects.
This project also can be used to determine the atomic composition of distant stars by measuring the light spectrum observing the color of flames when various...
