Unformatted text preview: Andrew T. Hedrick Chem 32 Section S 11/1/02 Experiment 8 Solution Conductivity: Covalent & Ionic Solutes Purpose: To relate bonding structure of substances to their behavior in solution, investigate electrical conductance of various aqueous solutions, and follow the conductance of a solution during the course of a chemical reaction. Experimental Plan: The instructions for this plan were based on The Thompson General Chemistry 2 Lab Manual, pages 91-100. Changes included using 5mL of deionized water as the solvent in Part IA. Data and Observations: Part IA: drops KI 1 2 3 4 5 6 conductivity (in mA) .0721 1.31 2.40 3.55 4.65 5.86 6.93 Part IB: Solution Conductivit y electrolyte? Solution Conductivit y electrolyte?
