electrolysis Flashcards
what is electrolysis?
the process of breaking down an ionic compound
what is an electrolyte
a liquid thats broken down by an electric charge
what are the electrodes ?
graphite rods that carry a current in and out of the electrolyte
what is the cathode ?
the negative electrode
what is the anode?
the positive electrode
what ions are attracted to the cathode ?
positive ions
what ions are attracted to the anode?
negative ions
can solid ionic compounds conduct electricty?
no
why cant solid ionic compounds conduct electricity ?
. because ions are locked in place cannot move around
. string electrostatic forces
what does molten mean?
melted
what do you do to a solid ionic compound to seperate the ions in electrolysis ?
melt it otheriwse electrolysis cannot be used
what reaction is it when negative ions go to the positive electrode?
a reduction reaction
what kind of reaction is it when the positive ions go to the negative elctrode ?
oxidation reaction
what is a reduction reaction?
. gain of electrons
. loss of oxygen
what is an oxidation reaction?
. loss of electrons
. gain of oxygen
