Experiment:Flame extinguishment of candles from the released carbon dioxide👨🔬👩🔬
16 June 2020
7th grade’s students explored in home conditions the carbon dioxide release and how that reaction can extinguish the flame of the candle.
Students made a chemical reaction between vinegar and baking soda, during which carbon dioxide is released as a gas. They tried to trap carbon dioxide. Carbon dioxide molecules are heavier than air. Because of this, they push the oxygen and other molecules in the air out of the way as they sink down over the flame and candle. When oxygen is pushed away from the wick, it can’t react with the wax anymore. This makes the flame go out.
