A student was asked by his teacher to perform a flame test on a solid. He used this method.● dip the tip of a clean platinum wire into hydrochloric acid and then into the solid● adjust the air hole of the Bunsen burner to obtain a non - roaring, non – luminousBunsen flame● place the tip of the platinum wire into the edge of the flame● observe the colour in the flame(a) (i) why is it important that the platinum wire is clean?
