To understand the components and processes of a galvanic cell.
A galvanic cell (or voltaic cell) produces electricity using a spontaneous redox reaction, such as the one shown here:
Fe(s) + Cu^2+(aq) → Fe^2+(aq) + Cu(s)
The components of this reaction are separated by a salt bridge and connected with a wire, forcing the electrons to travel across the wire, creating electricity.
The salt bridge is a U-shaped glass tube that is filled with a gel-like substance containing a salt. The salt bridge
