electrode

It will take some time for any cupric ions actually to reach the electrode and be deposited as metallic copper.

On the anode side, purple permanganate ions are seen rising toward the positive electrode.

The hydrogen electrode is connected with the negative post of the voltmeter, the oxygen electrode with the positive post.

For the purposes of this book it will be sufficient to limit our discussion to the behavior of an ideal oxygen electrode.

The gas is easily conducted to the platinum gauze electrode through such a tube.
