在新版高中化学(必修1)第二章“化学物质及变化”中,第2节在讨论离子反应时有这样一段叙述:“我们在初中曾观察过酸、碱、盐在水溶液中导电的实验现象。不仅如此,如果将氯化钠、硝酸钾、氢氧化钠等固体分别加热至熔化,它们也能导电。”这段叙述引出了在水溶液时或熔融状态下能导电的化合物叫做电解质这一概念。但笔者发现,无论在现行初中化学教材中,还是在高中化学教材中都没有关于该
In the second edition of Chemistry and Change in Chapter 2 of the new edition of Chemistry for Senior High School (Compulsory), Section 2 discusses the ionic reaction as follows: “We observed acid, alkali and salt in aqueous solution in junior high school In addition, if sodium chloride, potassium nitrate, sodium hydroxide and other solids were heated to melt, respectively, they can also conduct electricity. ”This statement leads to conductive compounds in aqueous solution or in a molten state Called the concept of electrolyte. But I found that no matter in the current junior high school chemistry textbooks, or in high school chemistry textbooks are not on the
