RedOx Flashcards
Oxidation number
Assigned charge
Oxidation
Loss of electrons; causes charge to rise
Reduction
Gain of electrons; causes charge to decrease
Voltaic cell
An electrochemical cell in which electricity causes a spontaneous reaction to occur
Anode
The part of a battery where oxidation occurs . (-)
Cathode
The part of a battery where reduction occurs. (+)
Nernst equation
Used to calculate cell potentials under non-standard conditions .
E E 0.0592/n (logQ)
Electrolysis
A non-spontaneous reaction caused to occur by application of electric current.
Electrolytic cell
An electrochemical cell in which electric causes a nonspontaneous reaction to occur
Ampere
Unit of electric current; A= Coulomb/second
Coulomb
Unit of electric charge produced by the flow of one ampere for one second.
Faraday
F= 1mole of electrons = 96485 coulombs
