【摘要】 Na2 S与K4 〔Fe(CN) 6〕在室温下反应不能马上产生FeS沉淀 ,其主要原因是由于〔Fe(CN) 6〕4 -水解或离解过程的晶体场活化能较高 ,因此提高反应温度或延长反应时间能够产生FeS沉淀 .更多还原

【Abstract】 The reaction between sodium sulfide and potassium ferrocyanide doesn’t immediately form ferrous sulfide at room temperature,the reason is the crystal field activation energy being high in hydrolysis and decomposition of ferrocyanide. So we can produce ferrous sulfide precipitate by raising reaction temperature or postponing reaction time.更多还原
