弱酸的电离常数是其性质的重要参数,相同条件下我们可根据其相对大小判断反应的可能性.一、试题品析(江苏泰州16年中考试题)“84”消毒液在日常生活中使用广泛,具有漂白、杀菌、消毒功效.某化学兴趣小组对一瓶敞口久置的“84”消毒液成分产生兴趣,在老师的指导下,展开探究.【提出问题】该敞口久置的消毒液中溶质有那些?【查阅资料】“84”消毒液主要成分是次氯酸钠(NaCl O)和氯化钠.Na Cl O为有效成分,有腐蚀性并易与空气
The weak acid’s ionization constant is an important parameter of its nature. Under the same conditions, we can judge the possibility of reaction according to its relative size. First, the test article analysis (Taizhou, Jiangsu 16 years examination questions) “84” disinfectant in daily life Widely used, it has the functions of bleaching, sterilization, and disinfection. A chemical interest group has an interest in a bottle of open and long-term “84” disinfectant composition. Under the guidance of a teacher, he explores it. [Problem] This exposure What are the solute in the disinfectant for a long time? [Refer to the data]“84” Disinfectant The main components are sodium hypochlorite (NaCl O) and sodium chloride. Na Cl O is the active ingredient, corrosive and easy to air
