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.

Question

L3 at Work
Two-component epoxy glues, such as
the one shown in Figure 6.5, contain two
parts: a resin and a hardener. The resin
is the glue and the hardener consists of
chemicals and a catalyst that determine
how quickly the glue will harden. The
rate of the chemical reaction can be
altered by changing the temperature or
the catalyst used in the hardener.
