一、例析与练习例 1 现有药品 :锌片Ｗ ｇ(Ｗ 1 )、稀硫酸、无水硫酸铜、氧化铜和水。请从下图中选用适当的实验装置 ,设计一个最简单的实验 ,粗略测定锌的原子量 (假设环境为标准状况 )。图 1　可供选择的实验装置( 1 )应选用的装置是 (只要求写出装置的标号 )　　。( 2 )所 First, analysis and practice examples 1 existing drugs: zinc tablets W g (W 1), dilute sulfuric acid, anhydrous copper sulfate, copper oxide and water. Please use the appropriate experimental setup from the figure below to design a simplest experiment to roughly determine the atomic weight of zinc (assuming the environment is a standard condition). Figure 1 The device that should be selected for the optional experimental device (1) is (only the device’s label is required). (2)
