Question

A standard hydrogen half-cell is connected to a standard zinc half-cell. The zinc is oxidized, and hydrogen ions are reduced. Which statement about the anode is true?

Option 1: It gains electrons
Option 2: It is the site of reduction
Option 3: It releases zinc ions
Option 4: It is the positive electrode

Answer 1

The anode in a galvanic cell is where oxidation occurs. In this case, the zinc electrode is the anode and is being oxidized. It produces electrons and is as the negative electrode.

Step-by-step explanation:

The anode in a galvanic cell is the electrode at which oxidation occurs. In this case, the zinc electrode is the anode because it is being oxidized. The balanced half-reaction for the oxidation of zinc is Zn(s) → Zn²+(aq) + 2e-. The anode is labeled as the negative electrode because it produces electrons.
