氧气是初中化学学习的一种非常重要的气体。氧气的实验室制法是同学们系统学习、研究的第一种气体的制法,为后面学习、研究制取其他气体如二氧化碳、氢气等打下了基础。下面对氧气实验室制法的考查点进行分析,帮助同学们熟练掌握这部分知识。 Oxygen is a very important gas for junior high school chemistry learning. Oxygen laboratory method is the first method for the students to learn and study systematically, which lays the foundation for the later study and research on other gases such as carbon dioxide and hydrogen. The following analysis of the laboratory points of oxygen laboratory analysis will help students master this knowledge.
