Concept explainers

Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.

<Homework on Chap 20 Electrochemistry
+ Gold Electroplating
Metal plating is done by passing current through a
metal solution. For example, an item can become
gold plated by attaching the item to a power source
and submerging it into a Au³+ solution. The item
itself serves as the cathode, at which the Au 3+
ions are reduced to Au(s). A piece of solid gold is
used as the anode and is also connected to the
power source, thus completing the circuit.
