let's see what i remember from class today...

[CHEM]

always true: oxidation at anode, reduction at cathode ('red cat')

it follows then that: e- flows from anode to cathode ('a cat')

more positive Eo (standard reduction potential) => more easily reduced

It = nF

dG = -nFEo

Nernst Equation: E = Eo - (RT/nF)lnQ (use for concentration cell questions)

Hendersen-Hasslebach: pH = pKa + log ( [A-]/[HA] )

"how much needs to be added to dilute..." <--remember already have the starting amount!
