- Please find standard deSo a Flame Test Investigation was conducted. In that activity, short wooden splints (sticks)were soaked in eight different chemical solutions. The splints were then held over a lit Bunsen burner oneat a time, at which time each one gave off a distinctive color of light Each splint produced a dominant, vibrant color, and the color was different for each one. Forexample, the splint soaked in copper chloride produced a green flame and the splint soaked in lithiumchloride produced a brilliant red flame. Please explain the following for me: 1. Why do chemicals give off light when heated by a Bunsen burner? 2. None of the chemicals produced “white light” similar to a common light fixture. In otherwords, none of the chemicals gave off the entire spectrum of visible colors. Why not? 3. Why does each chemical give off its own unique color that is different from every otherchemical? Give thorough explanations. Also, when explaining, correctly use each of the following terms at least…Suppose that a batch of parts is plated with Copper in an electrolytic bath running at 0.15V and 15A for exactly 2 hrs.
