Electrochemistry 

________= the negative ion which is attracted to the anode.

The ________ need to constantly be changed because thier mass decreases due to its reaction with oxygen.

________= the breaking down of ionic compounds using electricity.

A(n) ________ is lined with graphite which is attached to the- ve side of the battery making it the cathode, and three electrodes are connected to the +ve side of the battery making it the anode.

________ occurs and green bubbles are visible around the anode.

________= the positive ion which is attracted to the cathode.

The ________ is used to save time money and electricity.

________ which is positive and less reactive than the sodium is attracted to the negative cathode.

The ________ extracted can be used for aeroplane bodies, cans and food containers because it has low density, resists corrosion and is a good conductor.

________ and platinum are used because they are inert and good conductors.

The ________ gains gold atoms whereas the anode loses gold atoms.

The ________ extracted can be used in street lamps, salts and drugs whereas the chlorine can be used for bleaching and purification of water.
