IUPUI October 12‚ 2012 Titration of Acids and Bases Introduction According to Arrhenius definition‚ acid is substance that produces H3O+ ion while base is substance that produces OH- ions. The reaction between acid and base often yields the products of salt and water. The formation of water in this neutralization reaction is caused by the combination of H3O+ and OH- ions. In order to determine the concentration of an unknown acid and base‚ a method called acid-base titration is used. The end of

Date ___________________ NEUTRALIZATION TITRATIONS INTRODUCTION The neutralization of hydronium or hydroxide ion to form water is widely used as the basis for volumetric determinations of acids‚ bases and salts of weak acids. The reaction is characterized by a rapid change in pH near the equivalence point‚ a change that is readily detected by an acid-base indicator or that can be followed electrically by use of a pH meter. Neutralization titrations are performed with standard solutions of

Introduction A titration is a technique used to find the solution of known concentration in the concentration of another unknown solution. Typically‚ the known solution is added from a known quantity of unknown solution until the reaction is complete. Titrations are also often used to determine the pH of a solution. This is important because without knowing how acid or basic a solution is people could hurt themselves and others but mixing chemicals together that are lethal. The objective of the
