Lab Report - The Stoichiometry of an Oxidation-Reduction Reaction

Purpose: To find number of moles of Fe+3 which react with one mole of NH3OH+ in order to partially balance the equation: NH3OH+ + 2Fe+3 "" ? + 2Fe+2 and to find the missing product. Procedure: H2C2O4 and H2SO4 were titrated with potassium permanganate. The molarity of the permanganate was then found because the molarity of the H2C2O4 and H2SO4 were already known. Then hydroxylammonium chloride and ferric sulfate and water …

…determined to be N2O. Some systematic errors could be if the wrong molarity was determined for the permanganate because then that would though off the calculations for the Fe+2 and the rest of the equations, if equations weren't balanced properly, if some solutions spilled, if the buret wasn't rinsed, or if the flask was dirty. Some random errors would be the precision of the instruments used like the calculator, the buret, and the flask.
