氢氧化钙与碳酸钠：Ca(OH)2 + Na2CO3 === CaCO3↓+ 2NaOH （8）盐 + 盐 ----- 两种新盐 70．氯化钠溶液和硝酸银溶液：NaCl + AgNO3 ==== AgCl

无铵氯化物镀锌氯化铵对设备腐蚀严重,电镀废水处理困难,因此国内外电镀工作者对无铵氯化钾或氯化钠镀锌工艺进行了研究,并部分用于生产,实践证明无铵氯化物镀锌镀液深镀能力强,色泽光亮鲜艳,污水处理较简单.但是均镀能力低于铵盐镀液

例如，食盐即氯化钠分子中，碱金属钠元素的最外层只有1个电子，失去这个电子后就形成最外层有8个电子的稳定结构，而卤族元素氯最外层有7个电子，它获得一个电子后，最外层就形成了具有8个电子的稳定结构，因此，当两者相互作用时
