    • Abstract:
      A laboratory experiment characterized by a whole-class data-pooling approach to generate a data set that can be used to test a model of the influence of ionic strength on electrolyte solubility is described and discussed. The design of the experiment makes efficient use of the laboratory period and releases time for instructional and dialogic exchanges surrounding the theoretical background to ionic strength effects on ionic equilibria and the use of advanced features of Excel to analyze the data on the basis of a model derived from Debye–Hückel theory. The activity is assessed via a prelaboratory exercise and an Excel workbook, for which a typical data set with full analysis and results is provided.
