flow
electrons flow from oxidation to reduction sites
anode to cathode
sites of redox
anode always oxidation (vowels tgth)
cathode always reduction
galvanic cell
spontaneous flow
anode (neg) to cathode (pos)
electrolysis
non-spont flow
forced by external source
anode (+) to cathode (-) cus electrons are being forced to move in a way they dont want to go
reducing agent
experiences oxidation (loses electrons)
oxidizing agent
experiences reduction (gains electrons)
LEO
losing electrons oxidation
GER
gaining electrons reduction
concentration cell
same substance but different concentrations
flow from low concentration to high concentration
anode
oxidation
atoms become ionsĀ
mass loss from electrode, concentration in cell increases
cathode
reduction
ions become atoms
mass added to cathode, concentration decreases
