一、利用口诀巧记方程氨氧化法制硝酸中有三个步骤及三个方程式,学生不容易记忆,经常把方程式写错,根据步骤及反应,对氨氧化法制硝酸可编如下口诀:“高温催化氨氧化、一氧化氮和水生;一氧化氮再氧化,二氧化氮呈棕色;二氧化氮溶于水,要制硝酸就出来”。把氨氧化法制硝酸的三个步骤以及每步的反应物和生成物都表达清楚。 First, the use of the mouth to know the formula Ammoxidation method to make nitric acid in three steps and three equations, students are not easy to remember, often write the wrong formula, according to the steps and reactions, the ammonia oxidation of nitric acid can be edited as follows: “High temperature catalysis Ammonia oxidation, nitric oxide and aquatic; Nitric oxide reoxidation, nitrogen dioxide is brown; Nitrogen dioxide dissolved in water, to make nitric acid to come out ”. The three steps of ammoxidation to nitric acid and the reactions and products of each step are clearly expressed.
