氯水是中学化学实验常用的试剂,由于氯水中氯分子和水发生一定程度的化学反应,使得氯水的组成较为复杂,其性质也具有特殊性,因此成为中学化学教学中的难点,也是高考中经常考查的考点.一、氯水的组成氯水是氯气的水溶液,和氯气一样,也呈浅黄绿色.常温下,1体积的水可溶解2.26体积的氯气,假设水为1L,则可溶解氯气2.26L,忽略氯气溶于水时溶液体积的变化和温度的影
Chlorine water is a commonly used reagent in middle school chemistry experiment. Chlorine water has a complex chemical composition due to the chemical reaction between chlorine molecules and water in chlorine water, and its nature is also peculiar. Therefore, it becomes a difficult point in middle school chemistry teaching as well as a college entrance examination Chlorine water is a chlorine solution, like chlorine, but also pale yellow-green.At room temperature, a volume of water can dissolve 2.26 volumes of chlorine, assuming that the water is 1L, it can be dissolved Chlorine 2.26L, ignoring the changes in the volume of solution and temperature of chlorine dissolved in water
