Today we went to the lab to test how different chlorides reacted to fire and what colours they created. We did this by lighting a bunsen burner and using a metal spatula to hold different chlorides over top.
What we did was scoop a pinch of chloride on a little metal spatula, some of the ingredients we used were potassium chloride, copper chloride, magnesium chloride and a few more. After that we held the spatula over the flame and observed what colour the flame turned. We then recorded the results into a Google document. I think it's a good representation of what gives stars their colour because of all the chemicals burning in it cause different reactions.
