    Titration is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of a known reactant. Because volume measurements play a key role in titration‚ it is also known as volumetric analysis. A reagent‚ called the titrant or titrator‚[1] of a known concentration (a standard solution) and volume is used to react with a solution of the analyte or titrand‚[2] whose concentration is not known. Using a calibrated burette or chemistry pipetting syringe

    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
