electrolysis
the use of electricity to carry out a chemicle reaction
anode
positively charged electrode
cathode
negatively charged electrode
anions
negative ions
cations
positive ions
electrolyte
aqueous solution containing dissolved ions so it can conduct electricity
electroplating
where electrolysis is used to put a layer of one metal onto the surface of another
conditions needed for electroplating
the metal to be plated must be the negative cathode
the elctrolyte must contain ions of the metal we are plating with
the positive anode must be the metal we want to plate with
electrochemical series
a list of elements in order of their standard electric potentials
