| Abstract: | Three ways of reducing the ferric iron to ferrous iron can be used in iron determination from iron ore utilizing potassium dichromate.The experiment indicates that the method of SnCl2-HgCl2 has the best accuracy and precision,and the next is the way of TiCl3-Na2WO4,while using methyl orange as the reducing indicator has the biggest error. |
