全封闭式氨喷泉实验的新方法王锦化（徐州师范大学化学系２２１００９）氨喷泉实验是无机化学教学中能充分说明氨在水中具有很大溶解度的演示实验。由于经典实验方法［１］对氨和收集氨的装置的干燥程度要求高，稍有水分就易导致实验失败。另外当氨集满转换装置时易溢漏，... A New Method for Fully Enclosed Ammonia Fountain WANG Jinhua (Department of Chemistry, Xuzhou Normal University, 221009) Ammonia fountain experiment is a demonstration experiment in inorganic chemistry teaching that can fully explain the great solubility of ammonia in water. Due to the high degree of dryness of the ammonia and ammonia-collecting devices required by the classical experimental method [1], the slightest moisture can easily lead to experimental failure. In addition, when ammonia is full of conversion device overflow spill, ...
