Electrochemistry

This topic describes electrochemical cells. It can be defined as a device that is capable of generating electrical energy from chemical reactions. It can also use this energy to trigger chemical reactions.

This topic explains how galvanic cell devices are formed from the conversion of chemical energies into electrical energies. An illustration of the cell with its functions and cell notation, along with the role of salt bridge are discussed here.

This topic discusses electrode potential and standard electrode potential and its purpose in detail. We will also learn some methods of measuring these potentials with examples.

In this topic, we will learn about the potential difference developing in the cells along with the oxidation and reduction potential. We will also know about E.M.F. and compare it to PD.

This topic deals with the concept of electrolytic and metallic conduction. It also explains the factors affecting it with the help of examples and illustrations.

In this topic, we will learn about conductance in electrolytic solutions. This defines the ability of these kinds of solutions to conduct electricity. We will learn about the applicability of these kinds of measurements.

This topic shows the dependency of conductivity on the concentration of strong and weak electrolytes while diluting the solution. It also explains the conductance behavior of strong and weak electrolytes.

In the topic, we will study the law of determining molar conductivity of the electrolytes from the conductivities of cation and anion, respectively. It also mentions the applications of Kohlrausch’s law along with the examples based on this law.

In this topic, we will learn about electrolytic cells and electrolysis. Here we will learn that an electrolytic cell drives a spontaneous redox reaction through electrical energy. Electrolysis, however, is a technique that uses direct current.

This topic discusses the functioning of a battery. It is a source of electric current at constant voltage from galvanic cells. The details of the hydrogen-oxygen fuel cells and their advantages are also discussed here.

This topic explains that oxidation of the surface of a metal due to the action of atmospheric oxygen and water is known as corrosion. Corrosion of iron is called rusting. It can be prevented by galvanisation, chrome plating, alloy formation and electroplating.
