给吕萨克定律为学习初级化学的基础,通常以氢氧合成水来表明这个定律,但普通的中学很少有此种设备,同时其体积过小,不适于表演实验。若采用氧化氮(NO)与氧作用生成二氧化氮(NO_2),来表明此定律有以下数种优点:(1)不需要特殊设备。(2)形成有色的气体。(3)可以用比较大的体积。 To Lussac’s law as the basis for the study of primary chemistry, this law is usually expressed in water of hydrogen and oxygen, but ordinary secondary schools rarely have such equipment, while its size is too small, not suitable for performing experiments. If the use of nitrogen oxide (NO) and oxygen to produce nitrogen dioxide (NO2), to show that the law has the following advantages: (1) does not require special equipment. (2) Colored gas is formed. (3) can use a larger volume.
