Titanium dioxide (TiO2) is used extensively as a white pigment. It is produced from an ore that contains ilmenite (FeTiO3) and ferric oxide (Fe2O3). The ore is digested with an aqueous sulfuric acid solution to driving off water and leaving a residue of pure titanium dioxide. (Several steps to remove iron from the intermediate solutions as iron sulfate have been omitted from this description.) Suppose an ore containing 22.3% Ti by mass is digested with an 75.0%H2SO4 solution, supplied in 40.0% excess of the amount needed to convert all the ilmenite to titanyl sulfate and all the ferric oxide to ferric sulfate [Fe2(SO4)3]. Further suppose that 83.0% of the ilmenite actually decomposes. Calculate the masses ( kg ) of ore and 75.0% sulfuric acid solution that must be fed to produce 1000kg of pure TiO 2. kg ore kg75.0%H2SO4
