I. Stoichiometry of Chemical Reactions A. Moles/grams of Chemical Equations 1. Finding the mass of products B. Limiting Reactants 1. The reactant used up first in a reaction is the limiting reagent 2. Excess reactants are those present in quantities greater than necessary to react with the quantity of the limiting reactant 3. Determining the limiting reactant C. Reaction Yield 2. Theoretical yield is the amount of product that forms when all the limiting reactant reacts to form the desired product a. Done by calculations 3. Actual yield is the product actually obtained from a reaction a. Done by experimentation 4. Percent yield tells what percentage the actual yield is of the theoretical yield a. Percent yield = (actual yield) / (theoretical yield) x 100% D. Acid/Base Titrations 1. Equivalence point – point in titration where acid is neutralized 2. Titration – technique used in the quantitative studies of acid/base neutralization reactions 3. Color change brought about by the indicator
