During this lab we observed how binary Ionic compounds react when they absorb energy from the fire. Our compounds mostly changed color when they came in contact with the fire. The color changed depending on the compound. For example, LiCI created a vivid red color, NaCi did not create a new color but it showed strong oranges flames, KCI was pink, CaCI created a mix between orage and red. The one that really interested me was CuSO, which is a polyatomic ion, whom turned blue and green, also the fire caused chemical changes to create aluminum copper from it. The changes in color was better observed when the lights were out, during this time we can see how fast the flames change color. The changed in color is due to the electrons in each compounds
