One cold winter morning the temperature is well below0°F. In trying to start your car, you run the battery downcompletely. Several hours later, you return to replace yourfouled spark plugs and find that the liquid in the batteryhas now frozen even though the air temperature is actuallya bit higher than it was in the morning. Explain how thiscan happen.

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.
