“蜡烛不完全燃烧”实验的改进通过把蜡烛火焰调节为不完全燃烧状,并利用其火焰中的CO在高温下还原CuO,使黑色氧化铜变成红色铜的实验,验证蜡烛不完全燃烧的火焰中含有CO。实验操作简便,实验现象明显。 “Incomplete Burning of Candles ” Experimental Improvement The experiment was performed to verify that the candle was incomplete by adjusting the candle flame to an incompletely burned shape and using the CO in the flame to reduce CuO at a high temperature to turn black copper oxide into red copper The burning flame contains CO. Experimental operation is simple, obvious experimental phenomenon.
