氢气的实验室制取及性质是初中化学的重点内容之一。为此,改进氢气爆鸣实验装置,使其具有实用性强、成功率高、实验现象贴近真实的优点,对教师讲解氢气的燃烧现象和爆炸极限的概念起到了理想的辅助作用。同时,该改进装置能帮助学生掌握相关的化学知识,提高教师自身的创造力,符合新课标的教学理念。
Laboratory preparation of hydrogen and the nature of junior high school chemistry is one of the key elements. To this end, hydrogen hydrogen explosion experiment device to improve its practicality, high success rate, the experimental phenomenon close to the true advantages of the teacher explained the hydrogen combustion phenomenon and the concept of explosive limit has played an ideal auxiliary role. At the same time, the improved device can help students master the relevant chemical knowledge, enhance the teachers’ own creative ability, and conform to the teaching concept of the new curriculum standard.
