1.氯化钠晶体不能导电,是因为氯化钠晶体中不存在带有电荷的微粒,这句话对吗? 不对,因为氯化钠是典型的离子化合物,其中含有钠离子(Na+)和氯离子(Cl-),但由于阴、阳离子的静电作用,氯化钠晶体中的Na+和Cl-按一定规则紧密地排列着,只能在一定振幅范围内振动,不存在可以自由移动的离子.所以,干燥的氯化钠不导电是因为其中的带电微粒(即阴、阳离子)不能自由移动. 2.氯化氢溶于水可电离产生H+和Cl-,
1. Sodium chloride crystals are not conductive because there are no charged particles in sodium chloride crystals. Is this correct? Because sodium chloride is a typical ionic compound containing sodium ions (Na+) and Chloride ion (Cl-), but due to the electrostatic effect of anions and cations, Na+ and Cl- in sodium chloride crystals are closely arranged according to certain rules and can only vibrate within a certain amplitude range, there is no ion that can move freely Therefore, dry sodium chloride is not conductive because the charged particles (ie, anions and cations) cannot move freely. 2. Hydrogen chloride can be ionized to generate H+ and Cl- in water.
