PRESENTATION OUTLINE
Electrochemistry involves an oxidation reduction process. It's used in batteries, for different kinds of portable appliances, like flashlights. These are dry cell batteries.
Batteries have an anode, cathode, and electrolyte. The flow of electrons through a conductive path is called the circuit.
Cathode: the terminal where current flows out.
Anode: the terminal where current flows in from outside.
Oxidation-reduction is related to batteries because a galvanic cell in a battery package contains at least two half cells, a reduction cell and an oxidation cell.
Corrosion happens when electrolyte makes its way out to battery terminals through any leaks or joints. Overcharging heats up batteries and the increased heat can make the volume of electrolytes fill up.
RUSTING IS AN EXAMPLE OF ELECTROCHEMICAL CORROSION.
ELECTROLYSIS IN EVERDAY LIFE
- Hair removal (destroys the hair follicle- more permanent treatment)
- Creation of substances (calcium or magnesium. Used for building, bleaching, and sterilizing)
