The Equilibrium Constant of an Ester Hydrolysis Reaction Jesus Flores March 30th‚ 2015 Abstract: This experiment was conducted in order to discover the Kc‚ equilibrium constant‚ of a hydrolysis reaction of an unknown ester #2‚ unknown acid‚ and alcohol #2 products. The first week consisted of creating the reaction mixtures in bottles‚ next was preparing a NaOH solution while neutralizing with KHP. The final week consisted of titrating the bottles with the NaOH solution prepared previously
