The Solubility of Two Magnetite Powders in Oxalic Acid ...

AbstractIntroductionMethodsResults and DiscussionConclusionsAcknowledgmentsPhenomena-based models can be used in a predictive manner, but statistical modelling methods can also yield interesting findings and can serve as a tool for analysing the effects of different variables on the overall phenomenon. In addition, the generation of theoretical models can sometimes be limited due to the unideality of the studied system. Statistical modelling, in this case multiple-linear regression (MLR), was used to describe the effects of temperature and acid concentration on the dissolution of magnetite…

Iron(III) oxide - Wikipedia

Iron(III) oxide is insoluble in water but dissolves readily in strong acid, e.g. hydrochloric and sulfuric acids. It also dissolves well in solutions of chelating agents such as EDTA and oxalic acid. Heating iron(III) oxides with other metal oxides or carbonates yields materials known as ferrates (ferrate (III)): ZnO + Fe 2 O 3 → Zn(FeO 2) 2

Jan 03, 2013· The smaller effect of the acid concentration could be explained by the dissolution of impurities from the industrial material: impurities with higher solubility than Fe oxide consumed the acid. Consequently, the apparent increase in acid concentration was not completely directed at the dissolution of iron resulting in a smaller total effect.
