### Eo as an intensive property

Why exactly is Eo intensive?

### Re: Eo as an intensive property

Eo is measured under standard conditions and it is a measure of the electron-pulling power of a single electrode.

Therefore, it's a property of matter that does not change even if the amount of matter changes.

It is similar to the density of water. Even though you change how many electrons (by changing the coefficient), it won't affect the the E nought value of the each material.

### Re: Eo as an intensive property

It is intensive because it is measured under standard conditions

It does not change even with a variable change in matter.

### Re: Eo as an intensive property

Because intensive properties do not change when amount of substance is changed, this is most relevant when it comes to balancing redox reactions. Multiplying an entire half reaction by any constant does not change Eo.

### Re: Eo as an intensive property

Could someone explain why Eo doesn't change when the amount of matter changes? Does this mean that the maximum potential of a battery stays the same no matter how much of the reduced and oxidized substances you have?

The property does not change no matter how much of it occurs. Therefore if we must balance a reaction we can't change $E^{\circ}$

Eo is standard cell potential. It is E at 25C.1atm.1M (standard conditions).
