摘要
用甲醛法对硝酸铵中氮的百分含量进行了滴定分析研究。研究结果表明，硝酸铵可以与甲醛进行定量反应。利用该反应释放出来的质子，用标准氢氧化钠溶液进行滴定。
The percentage of nitrogen in ammonium nitrate has been studied by acid- base titrimetry,this experiments show the NH_4NO_3 can give off H^+ quantitatively after re- acting with HCHO.The percentage of nitrogen in ammonium nitrate can be determined by titrimetry with standard NaOH solution.
