中学化学的几个新制问题哈尔滨市香木中学刘良玉一、饱和氯水氯水是氯气的溶液，氯气溶于水后能够跟水发生歧化反应，离子方程式为：Ｃｌ２＋Ｈ２Ｏ＝Ｈ＋＋Ｃｌ－＋ＨＣｌＯ该反应的平衡常数Ｋ＝［Ｈ＋］［Ｃｌ－］［ＨＣｌＯ］［Ｃｌ２］＝４．２×１０－４，常温下１０...
Several new problems in middle school chemistry Harbin Xiangmu Middle School Liu Liangyu 1. Saturated chlorine water Chlorine water is a solution of chlorine. After chlorine is dissolved in water, it can disproportionate with water. The ion equation is: Cl2+H2O=H++Cl-+HClO The equilibrium constant of this reaction K=[H+][Cl-][HClO][Cl2]=4.2×10-4, at room temperature 10...
