From the experimental results. The color of the flames caused by the transition element. Can conclude that compounds of transition metals, which is taken as an element of the wax candle? When the fire has a different color as follows: CuSO 4 _ green, purple, and KNO 3 _ NaSO_ (4), Orange by comparison experiments made with candles using aqueous solution of the three substances be made soluble by water and HCl, that the color of the flame to the most obvious is that it was done so with HCl leaching substances be made soluble by water and HCl are stuffed, candles will make the color of the flame over the substance that is dissolved with water because the HCl will help elements transition ignite for a long time.
