Final answer:
In a galvanic cell, oxidation occurs at the anode and reduction occurs at the cathode. The anode is the negative electrode, while the cathode is the positive electrode. The shorthand notation for the cell is to write the anode on the left side, followed by a vertical line, then the cathode on the right side.
Step-by-step explanation:
In a galvanic cell, the half-reaction that occurs at the anode is the oxidation half-reaction. This involves the loss of electrons and the conversion of a species into its ion form. The half-reaction that occurs at the cathode is the reduction half-reaction, which involves the gain of electrons.
In this cell, the electrode on the left (anode) is where oxidation occurs, and the electrode on the right (cathode) is where reduction occurs. The anode is always the negative electrode, while the cathode is the positive electrode.
To represent the cell in shorthand notation, the anode is written on the left side, followed by a single vertical line that represents the salt bridge or separator, then the cathode is written on the right side.
