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.

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.

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

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