11. Chemical Effects of Electric Current
The chapter discusses the chemical effects of electric current, particularly how it interacts with various materials and liquids. It explores the conduction of electricity through liquids, the chemical reactions that occur when current passes through solutions, and the process of electroplating. Through a series of experiments, the distinctions between good and poor conductors of electricity are established, revealing the importance of understanding these concepts in practical applications and safety.
Sections
This section explores how electric currents can chemically affect materials, especially liquids, and introduces the concept of electroplating.
Some liquids are good conductors of electricity and some are poor conductors.
Most liquids that conduct electricity are solutions of acids, bases, and salts.
The passage of an electric current through a conducting liquid causes chemical reactions.
Conductor
A material that allows electric current to pass through it easily.
Electroplating
The process of depositing a layer of any desired metal on another material by means of electricity.
LED
Light Emitting Diode, a semiconductor device that emits light when current flows through it.
Chemical Effect of Electric Current
Reactions that occur in a solution when an electric current passes through it, leading to changes like gas production or deposition of materials.
Electrode
A conductor through which electricity enters or leaves an object, solution, or region.
