Tabulation of Data: Place approx. 10 mL of assigned solution in a 100 mL beaker and test for consuctance. (Group assigned with distilled water will be the first one to test for conductance.) Immerse the electrodes one cm apart into the liquid or solution (Note 1). Note the intensity of the glow of the light bulb. Describe the glow as being: bright, dim or none. The conductance of the other 1.00 M solutions will then be tested. For 2.00 M solutions, combine NH 3 and HCl in equal volumes. Do the same for NH and CH COOH. Observe what happens to the conductance of the glacial CH 3 COOH upon successive dilutions with 10 mL of distilled water (Note 2). Record your results....
