化学实验是化学课程的灵魂,又是进行科学探究的重要方式.在新一轮课程改革的推动下,各中学都在不断加强化学实验室的建设,为满足中学化学实验的需求,储备一定数量的化学仪器和化学药品,然而由于化学药品本身的不稳定性及外界条件的影响,使得化学药品易发生变质.不仅造成经济上的损失,而且影响化学实验的成败,同时对化学实验室的环境造成一定的污染.因此,有必要通过对变质原因的探讨,找到妥善保管化学药品的方法.
Chemistry experiment is the soul of chemistry course and an important way to carry on scientific inquiry.Under the reform of a new round of courses, all secondary schools are constantly strengthening the construction of chemistry laboratories, reserving a certain amount to meet the needs of high school chemistry experiments However, due to the instability of the chemical itself and the external conditions, the chemicals are easily deteriorated, which not only causes economic losses but also affects the success or failure of the chemical experiment, and at the same time, the chemical laboratory and the chemical environment Resulting in a certain degree of pollution.Therefore, it is necessary to explore the causes of deterioration, to find ways to properly store the chemicals.
