These chmicals were soaking on an end of a stick which we were given. WE got those sticks and burned them on a bunsen burner to see what color it produces.

We determined our unknown to be Sodium. It was sodium because they had similiar colors plus we did sodium right before out unknown making it easier to see it was sodium.

Each chemical has there own unique color.

One question if we mixed chemicals that produce red and green would it be able to produce the color blue?
