我们做碳还原氧化铜的实验时,不需要喷灯,操作简便速度快现象明显。现介绍于后: ①所用炭粉:用活性炭效果好,要事先把活性炭放入蒸发皿里加热以除去所吸附的水分。如果没有活性炭用一般木炭也可,需先把木炭块在酒精灯焰上烘烤以除去水分再研细。 When we did the experiment of carbon reduction of copper oxide, no torch was needed, and the operation was simple and fast. Now introduced in the following: 1 used charcoal: the effect of using activated carbon is good, prior to putting the activated carbon into an evaporation dish to heat to remove the adsorbed water. If you do not use charcoal for activated charcoal, it is necessary to first bake the charcoal block on the flame of the alcohol lamp to remove the water and then study it.
