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!
