Ani Keliiheleua16 April 2020Gen Chem LabAcid Base TitrationTitrations are used to find the unknown concentration of a reactant within a solution. Toperform a titration, a known reactant, or the titrant, is slowly added to a reactant of unknownconcentration, the analyte. The progress of the reaction can be monitored in a number of wayswhich can indicate the point at which the reaction is complete. In this investigation, the titrationwas monitored using a pH probe because pH is the most accurate way to monitor an acid/basereaction. Graphing this data will present the equivalence point, or the point at which moles oftitrant are equal to the moles of analyte. Stoichiometry is used to understand the relationshipbetween molar amounts of species in a reaction. This concept is implemented frequently duringtitrations. The equivalence point also indicates the completion of the reaction.Afterunderstanding when the equivalence point is reached, volumes of species can be calculated andused to determine the analyte’s unknown concentration. This will lead to the calculation ofmass percent. These concepts and methods help guide us to answering the question “What isthe mass percent of acetic acid in vinegar?”
