1、氨气实验室制法的研究与改进吐逊阿衣·艾买提（一）氨气的实验室制取方法一1、实验仪器和药品仪器:铁架台、铁夹、酒精灯、木砖、试管、试管塞、三通管、橡胶管、止水夹、橡皮筋、玻璃导管、集气瓶、双孔橡皮塞、药匙、火柴。药品:氯化铵、消石灰、红色石蕊试纸、蒸馏水。2、实验装置图（如图1）图1A.用于加热反应物B.用于收集氨气C.用于检满D.用于吸收多余的氨气E.用于防止倒吸a.氯化铵和消石灰混合物b.润湿的红色石蕊试纸①,②,③,④均为止水夹3、实验操作步骤（1）按图装好仪器，打开①、②、③、④，在D中装入水或稀硫酸，E中装入水。（2
2、）检查气密性:用酒精灯稍微加热试管A，若D中有气泡产生，则已密封好。（3）用橡皮筋装好润湿的红色石蕊试纸b。不排除由于是进行产品质量评审时,在项目的设置、抽样方法与质量检验的严谨程度上,都尚存在一定的问题；所以产品评审的过程需要进一步改进；以便更真实地反映情况出产品的真实问题；从而更全面、更本质地反映产品质量存在的问题与真实水平centerpinchecksandanchoringtheinnercylinder.AccordingtoWhilecouplingalignmentshouldkeepoiloutofcavit
