Final answer:
In a galvanic cell, the anode is where oxidation occurs, while the cathode is where reduction occurs. The anode is negatively charged, and electrons flow from the anode to the cathode.
Step-by-step explanation:
In a galvanic cell, the anode is the electrode where oxidation occurs, and the cathode is the electrode where reduction occurs. Electrons flow from the anode to the cathode. The anode is negatively charged, while the cathode is positively charged.
For example, in a galvanic cell with a zinc strip and a hydrogen electrode, the zinc strip acts as the anode, where zinc atoms dissolve and release electrons. The hydrogen electrode acts as the cathode, where hydrogen ions are reduced to form hydrogen gas.
By following the flow of electrons and the location of oxidation and reduction reactions, you can determine which electrode is the anode and which is the cathode in a galvanic cell.
