Electrical potential vs Reductive potential.

If I'm given a series of 2x electrolytic cells with a power source of 2 A, 0.5 V, why can't this reduce the following reaction with reduction potential of -2.91?

Na+ + e– → Na –2.71

The voltage, not the amperage, is what's important in determining whether something will be made. Amperage determines how quickly.

Ok, thanks

so my question is 2x 0.5 V (positive) is not enough to reduce the -2.71. Is this just sign convention or something?

Think about it - you need a net positive potential to run, right? How does 1 (2x0.5) compare to -2.71?

oh ok thanks 🙂
