Magnetite is the mineral form of black iron oxide (FeO). It often occurs with magnesium (Mg), zinc (Zn), and manganese (Mn) and is an important ore of iron. The answer is Iron (Fe).

Manganese - Mn Atomic Weight - 54.9380 Atomic # - 25
Percent by weight: Carbon (C) 3.70, Silicon (Si) 2.50, Manganese (Mn) 0.40 The rest is iron (Fe)
The Mn+7 ions (purple) are reduced to Mn+4 ions (brown), unless some diltue sulfuric acid has been added to the solution. This will make the Mn+7 ions reduce fully to Mn+2 ions (colourless). The end point of the reaction is gotton when there is a permanent pale pink tinge left in the conical flask. (The Potassium Permangante should be in a Burette and be released slowly into the flask containing the Iron Sulfate). HOWEVER: Iron sulfate gets oxidised by Oxygen in air and water and undergoes hydroylisis of water. Therefore you should use a primary standard like Ammonium Iron II sulfate for this reaction.
