Galvanic Cells

Electrochemical Cell

A cell that converts chemical energy to electrical energy (or vice versa)

Galvanic Cell

A cell which converts chemical energy into electrical energy (used in mobile phones and laptops)

Battery

Combination Of Cells

Used to describe cells as well in common day language

External Cicrcuit

Wire that flows outside of the circuit connecting the electrodes

Why The Electrolyte In The Salt Bridge Is Unreactive

If it were reactive, it could participate in chemical reactions, form precipitates, alter cell potential

As it is unreactive, it is only a spectator ion

Spontaneous Reaction

No need for external energy

The reaction happens naturally, and by itself

Primary Cells

Cells that are used once, and cannot be recharged

Alkaline Cells

Cells that are non-rechargeable, once the equilibrium has been reached

Equilibrium

When there is a large chemical potential difference (EMF) between the anode and cathode

anode (has a large driving force to donate electrons)(

cathode (has a large driving force to obtain electrons)

The force slowly depletes as the battery discharges, and charges balance out

Potential Difference/Electromotive Force

In reference to the disparity between anode and cathode

One has a higher tendency to attract electrons, whilst one has tendency to donate

The force is referenced as voltage
