m a coating on oneof the electrodes which tends to insulate the cell and also to change its polarity. This effect is termed polarization. Polarization. Experiment 40. Place a zinc and copper electrode Fig. iio.-Polar- -^^ ^ solution of H.SO^ so that but a small part of the electrodes is immersed;… … move. Heat the electrodes over a bunsen burner, and repeat the ex-periment, showing the effects of polarization. The heat of the flamewill drive off the polarizing gas. Experiment 41. Repeat the experiment, substituting a low-rangevoltmeter for the bell, and notice that the deflection of the…
