To determin the amount of Fe in a sample, a 3.735 g of sample is dissolved in suitable solvent, giving a Fe3+ solution, then, Fe3+ ion is precipitated completely as Fe(OH)3. Filtering, rinsing, and igniting the precipitate at 1000C provides 1.705 g of one pure compound. a. Which reagent is best suited to completely precipitate Fe3+ ions? b. Write the diagrams or the chemical equations are described in the above analysis process? c. Calculate the gravimetric factor (GF) and the %w/w Fe in the sample. Given Fe = 56; O = 16.
