A student sets up a simple cell using the two half-cells described below.
Half-cell 1: a silver electrode in contact with ions,
Half-cell 2: a copper electrode in contact with ions,
The standard electrode potentials are:
Describe how the student can use these standard electrode potentials to deduce the polarity of each electrode and the direction of electron flow in the external circuit of this cell. Include in your answer which electrode is the positive electrode and which is the negative electrode, and state the direction of electron flow.
