12 Acid Base Titration 14:38:39 Dustin Damashek Steven 85 103b-149 Intro This experiment gives the opportunity to learn about volumetric analysis by doing a titration and learn how to use a buret Educational Objective Perform an acid base titration using a suitable indicator to detect the endpoint Properly use a buret and a pipette Demonstrate reproducibility through trials Use the results of a titration to determine moles of a compound in a sample Experimental Objectives Prepare a solution of sodium hydroxide Standardize the NaOH solution against a primary standard Perform a back titration to determine the antacid capacity of a commercial product Water is an essential chemical in our world. Perhaps the most important aspect of chemistry of water is its dissociation into acid and base
