loss of electrons
gain of electrons
something that is being duced by taking electrons from something else
something that is being oxidized by reducing something else
Oxidation # rules
a) elements are zero
b) in componds
i) oxygen is -2 (except in peroxide)
ii) group 1 and group 2 are +1 and +2
iii) Hydrogen is +1 (unless with metals)
(-) where oxidation occurs and where electrons are produced
(+) where reduction occurs and where electrons are used
Relatively negative Ered means...
"likes" to lose electrons (oxidation) -> anode
Relatively positive Ered means...
"likes" to gain electrons (reduction) -> cathode
Electrons go from _______ to _______.
Electrons go from ANODE to CATHODE.
If you get a negative net Ecell than...
the equation is "backwards."
When at equilibrium cells are ______ and voltage is _______.
When at equilibrium cells are FLAT and voltage is ZERO.
Ecell = E˚cell - 0.0592/n * logQ
Charge (Q) =
Faraday's constant =
96,500 C/mols of electrons
