K2Cr2O7法测定Fe2+实验微型化研究
Study on determination of Fe2+using K2Cr2O7 titration experimental miniaturization
摘要
Abstract
The feasibility and the range of concentration in the miniaturization experiment about the Fe2+content of the ferrous salt was studied through using adapted micro type burette.Keeping the basic operation,using F-test and t test,comparing with constants titration,when reagent consumption reduced to 1/5,the precision declined,but it can still basically meet the students' experiment requirement.The preferred concentration range for standard solution of K2Cr2O7 is 0.009 4~0.034 0 mol/L.关键词
