What is the fundamental equation for calculating total voltage of a redox reaction?

Etotal=Ered+EoxidE_{\text{total}} = E_{\text{red}} + E_{\text{oxid}}

How do you find the voltage for an oxidation half reaction from standard electrode potentials?

Reverse the sign of the reduction potential

What happens to electrode potential when you double a half equation to balance electrons?

The potential value stays the same

What does a positive cell voltage indicate about a redox reaction?

The reaction is spontaneous as written

What does a negative calculated voltage tell you about the reaction direction?

The reverse reaction is spontaneous

Which electrode becomes positive in a galvanic cell?

The one with higher electrode potential

What equation is used when you don't know which electrode is positive?

Ecell=εA−εBE_{\text{cell}} = \varepsilon_A - \varepsilon_B

A cell voltage of 1.62 V means the reduction electrode is how much more positive than the other?

1.62 V positive
