To start a stoichiometry problem I need to write and balance the chemical equation for iron sulfate (FeSO4) and potassium dichromate (K2Cr207). I don‘t know what compounds will result. This is the question if anybody cares:A 3.33 gram sample of iron ore is transformed to a solution of iron (II) sulfate, and this solution is titrated with 0.150 M potassium dichromate. If it required 41.4 mL of potassium dichromate solution to titrate the iron (II) sulfate solution, what is the percentage of iron in the ore?
