Galvanic Cells

Anions from the salt bridge flow toward

the anode to neutralize the build- up of positive charge.

oxidation

As the ________ occurs, a surplus of positive ions builds up at the anode.

Electrons

________ move through an external wire from the anode to the cathode.

spontaneous redox reaction

In principle, any ________ can serve as a source of electrical energy in a galvanic cell.

salt bridge

The ________ is a porous material consisting of a concentrated salt solution.

Salt bridge

________: supplies additional cations and anions needed to balance out these charge differences and complete the circuit.

Anode

site of oxidation

Cathode

site of reduction

Salt bridge

supplies additional cations and anions needed to balance out these charge differences and complete the circuit

Cations from the salt bridge flow toward

the cathode to “replace” the cations that are being consumed.

Anions flow to the

anode

Cations flow to the

cathode
