硫酸铁(Ⅱ)铵浓度的测定 应用资料

智能文字提取功能测试中

硫酸铁(Ⅱ)铵浓度的测定 应用资料检测0.1mol/L硫酸铁(Ⅱ)铵溶液的浓度。在稀释的样品中加入浓硫酸并冷却后，用0.02mol/L高锰酸钾溶液进行滴定。终点是滴定曲线上的最大拐点。硫酸铁(Ⅱ)铵的浓度由高锰酸钾溶液的滴定体积计算得出。KM KYOTO ELECTRONICSMANUFACTURING CO.，LTD.TIZ-99075enL Application Memo Determination of Ammonium Iron Sulfate( ii ) Concentration Industry Inorganic chemical industry Instrument Automatic potentiometric titrator Measurement methodRedox t i tration StandardsGB/T 601 1.Overview The concentration of 0.1mol /L ammonium i ron sul f ate (ii) solution i s examined. After adding concentrated sul f uric acid to the diluted sample and cooling， i t is titrated with 0.02mol/L potassium permanganate solution. The endpoint i s the maximum inflexion on the titration curve. The ammonium iron sulfate (ii ) concentration is calculated from the titration volume of the potassium permanganate solution. 2.
