Nichrome wire loop is first dipped into a solution of the respective compound (H3BO3, NaCl, LiCl, KCl, Fe(II) Fe(NH4)2(SO4)2, BaCl2, SrCl2, CaCl2, Cu(NO3)2). It is then brought into the flame from propane Bunsen burner, producing a color. The color of the flame is determined by the element's emission spectrum which is characteristic to that element.
