Can completed a lab in chemistry class that involved placing samples of current ionic salts into a flame and observing the color produced. He noticed that he saw three main colors in the experiment, despite using eight different salts (Copper chloride, sodium chloride, potassium chloride, copper sulfate, sodium carbonate, potassium carbonate, copper nitrate, sodium sulfate.). What hypothesis could cam investigate as a result of this initial experience? What data should he collect
