GALVANIC CELL

HISTORY

• Scientist Luigi Galvani discovered that he could make the leg muscles of a dead frog contract by connecting two different metals to each other then connecting it to the leg with them at the same time. Galvani called it "animal electricity," while his partners called it galvanism.

WHAT IS A GALVANIC CELL?

• The Galvanic cell, also known as the voltaic cell, is part of a battery consisting of two metals joined by a salt bridge

HOW DOES IT WORK?

• half of the metal oxidizes, in the other cell, the cations in the solution gain electrons, losing their negative charge, and becoming stable metal molecules that collect on the electrode. If the circuit is connected with wires leading from each electrode and making contact with each other.The half-cell that releases cations is known as the anode, and the one that attracts cations is called the cathode.

WHAT IS IT USED FOR?

• Batteries

WHAT IS IT MADE OF?

• A material that gets oxidized such as zinc a material that gets reduced two electrodes (cathode and anode) where the reactions take place and where the battery can be connected to an external circuit to provide power; and an internal salt bridge to complete the electrical circuit
