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:
Sn(s) + Cu^2+(aq) → Sn^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 completes the circuit and allows ion to flow, maintaining electrical neutrality in the solutions.
