  • @Tutimpulse For a voltaic cell: cathode = positive electrode, anode = negative electrode.

    For an electrolytic cell: cathode = negative electrode, anode = positive electrode.

  • hey is the cathode connected to the +ve or -ve side of the battery?

  • The gold doesn't randomly get 3 electrons.

    The gold gives up 3 PROTONS.

    The result is Au+3 ions and Au-3 ions.

    Hope that answers your question.

  • thanks

  • How does the gold cathode randomly get 3 electrons.

    Please answer.

  • i think u got cathode and anode mixed up.

    cathode = positive electrode.

    anode = negative electrode.
