Stoichiometry of a Neutralization Reaction & Aluminum Leftovers Labs By: Blaze Burnell February 2, 2013 Abstract: The objective of these two labs was to observe how important stoichiometry is in the world of chemistry to understand reactions, predict amounts of reactants needed and products produced, and to determine the identity of unknown substances. Stoichiometry is the branch of chemistry concerned with measuring the proportions of elements that combine during chemical reactions(Bing). The importance of stoichiometry was reinforced through a single replacement reaction and a titration experiment. Both of these experiments along with many others throughout the chemistry world relied fully on stoichiometry and a good understanding of the periodic table in order to finish the required calculations. Introduction: Stoichiometry is the branch of chemistry concerned with measuring the proportions of elements that combine during chemical reactions (Bing). The mole ratio, which is the comparison of moles of a given reactant or product in an equation, is essential to the proper usage of stoichiometry. In the following experiments, stoichiometry and mole ratios were used to accurately predict and obtain missing proportions from the given equations. In the stoichiometry of a neutralization reaction experiment, the molarity and type of acid were predicted by the titration of an unknown acid using .1 molar (M) Sodium Hydroxide (NaOH). In the other, aluminum leftovers, the activity series was used to understand how and why the reaction took place and stoichiometry was used to predict the amount of aluminum that should have reacted in the following equation: 3CuCl2 * 2H2O (aq) + 2Al (s) 2AlCl3 (aq) + 3Cu (s) + 6H2O Stoichiometry’s importance in the laboratory is well defined in the results of the previously mentioned experiments.
