Purpose and Method The purpose of the laboratory is use our knowledge of stoichiometry in a hands-on experience. Stoichiometry refers to the calculations of the different quantities of the reactants and products of chemical reactions. In our experiment, we will use Stoichiometry to figure out the chemical equation of the reaction between hydrogen peroxide and bleach. Experimental Procedure For the experiment, a setup was made as follows: For each trial, the same amount of bleach …

…volume of Fe(II) added to the solution and the amount of absorbance that was observed. After a while, the amount of absorbance leveled off at around .30. This indicates that the Phen is now the limiting reagent and Fe(II) now is in excess. From the calculation of n, we can conclude that in the chemical equation of 1,10-Phenanthroline and Fe(II), there are about 144 times more moles of Phen than there are Fe(II).
