Lab demonstrating the formation of ions by showing the property of electrical conduction when ionization occurs. A sample of purified water is tested for conductivity as a base solvent. A variety of solids in powder form are tested for conductivity using a voltmeter. The substances all proved to be non conducting. After solution formation, each was tested again with the results noted. All solutions which now demonstrated conductivity were noted and their ionization formulas written to show ions formed.
