高中化学課本第一册第五章第十一节涉及到这样一个小問題:“……三氧化硫跟水化合就生成硫酸:……当三氧化疏导入盛有少量水的玻璃杯时,就立卽跟水化合生热而形成白色酸霉,这些酸雾是散布在空气里的极小的硫酸液滴,不易被水完全吸收,因而大部分随着气泡逸出,所以这样只能制得一些稀疏酸。”至于为什么会有上述的情况出现?以及在工业生产上采用浓酸来吸收三氧化硫的问题未作进一步的闡明,因而在教学中往往給以忽视,不把它作为讲授的內容,結果給中学生留下了比較模糊的印象,知其然不知其所以然。为了給中学生讲明白这个問題,作者认为:若能按
High school chemistry textbook first chapter fifth chapter eleventh section relates to such a small problem: “... ... sulfur trioxide and hydration generate sulfuric acid: ... ... when the trioxide into the glass with a small amount of water, when Riga and hydration heat and the formation of white mold, the acid mist is scattered in the air in the tiny droplets of sulfuric acid, not easily absorbed by the water, so most of the bubble with the escape, so this can only be made Some sparse acids. ”The question of why this is happening and the problem of using concentrated acids to absorb sulfur trioxide in industrial production have not been further elucidated and are therefore often overlooked in teaching and not taught as such Content, the results left a relatively vague impression of secondary school students, knowing that although I do not know why. In order to clarify this problem for middle school students, the author thinks: If you can press
