Questions & Step-by-Step Solutions
In a galvanic cell, what is the function of the external circuit?
Step 1: Understand that a galvanic cell has two parts: the anode and the cathode.
Step 2: Know that the anode is where oxidation happens (loss of electrons) and the cathode is where reduction happens (gain of electrons).
Step 3: Realize that electrons need a way to travel from the anode to the cathode to complete the circuit.
Step 4: The external circuit is the pathway that allows these electrons to flow.
Step 5: This flow of electrons generates electric current, which can be used to do work.
Galvanic Cell Functionality – The external circuit allows for the flow of electrons, facilitating the redox reactions occurring in the galvanic cell.
