Using Conductivity Measurements to Determine the Identities and Concentrations of Unknown Acids: An Inquiry Laboratory Experiment
Smith, K. Christopher; Garza, Ariana
Journal of Chemical Education, v92 n8 p1373-1377 Aug 2015
This paper describes a student designed experiment using titrations involving conductivity measurements to identify unknown acids as being either HCl or H[subscript 2]SO[subscript 4], and to determine the concentrations of the acids, thereby improving the utility of standard acid-base titrations. Using an inquiry context, students gain experience with titrations, conductivity, procedural design, and analysis of results. The results of the experiment indicate that it is robust enough for use with advanced high school or college general chemistry students.
