Card Set Information
Oxidation Is Loss
Reduction Is Gain
any device in which chemical energy can be converted to electrical energy or vice versa
oxidation and reduction occur in
2 separate cells
redox reaction is
both oxidation and reduction in
electrolytic reduction, electroplating
electrons are lost
Voltaic - negative
(VAN Voltaic Anode is Negative)
Electrolytic - positive
(APE - Anode Positive in ELectrolytic)
Voltaic - cathode is positive
electrolytic - cathode is negative
How Electroplating Works
Battery provides energy needed for nonspontaneous reaction.
When switch is closed, electrical energy will force oxidation and reduction reactions to occur.
At the Anode, Ag loses e- and becomes Ag
At the cathode, Ag
gains e- and becomes Ag. The silver is coated onto the spoon.
