Fe2O3 + C = FeO + CO2 – this reaction occurs under the influence of a temperature of more than 1500 degrees. During the forging of metal in a coal forge, excess oxygen is taken up by the coal, forming iron oxide and carbon dioxide.
FeO + 2HI = FeI2 + H2O – iron oxide reacts with hydrogen iodide to form iron iodide and water.
FeI2 + 2NaOH = Fe (OH) 2 + 2NaI – iron iodide reacts with sodium hydroxide to form sodium iodide and iron hydroxide.
