人教版全日制高级中学教科书《化学》(必修加选修)第二册第六章第三节“有机物分子式和结构式的确定”中用了如图1的实验方法测定无水乙醇与钠反应生成H2的体积。反应前,在洗气瓶中装满水,此时导管的a-b段内有水柱,而导管b-c-d-e-f段内无水柱。当0.1mol无水乙醇与足量Na发生反?
People’s Education Edition full-time high school textbook “Chemistry” (compulsory optional) Volume II, Chapter VI, Section III “Determination of molecular formula and structure of organic matter” using the experimental method as shown in Figure 1 Determination of anhydrous ethanol and sodium reaction H2 volume. Prior to the reaction, the scrubbottle was filled with water, at which time the water column was in the a-b section of the conduit and the water column in the b-c-d-e-f section of the conduit. When 0.1mol anhydrous ethanol and sufficient Na anti-reaction?
