To solve these problems, we present a simple and feasible method for preparing molybdic acid ammonium solution. Ion identification experiment results showed that molybdic acid ammonium solution prepared by our method was sensitive to phosphate ion. The whole process was specific to phosphate ion, and we achieved satisfied experimental result in the teaching experiment. After storing the molybdic acid ammonium solution prepared by our method for 1 year, the ion identification experiment showed similar result for phosphate ion identification, solving the short shelf-time problem of molybdic acid ammonium solution in the inorganic chemistry teaching experiment. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书修改说明 -->
