Introduction Daniell cell converts a chemical form of energy into electrical energy. Lets learn more about it. How does the battery in a mobile phone charge when it is plugged into its charger or how does the cell in a TV remote control function? The study of electrochemistry includes both the use of electricity to conduct non-spontaneous chemical reactions as well as the production of electricity through chemical reactions. Cells are employed to attain the goal. Cells are components that cause chemical reactions that result in electricity or generate electricity. What are the two types of cells? ... Read More

Introduction By combining the words "electrolyte" and "conduction" or "conductors, " the phrase "electrolytic conductance" is created. It is crucial to first realize what each of these terms means. A material that generates electricity when dissolved in a polar solvent like water is known as an electrolyte. These electrolytes cannot conduct electricity in a solid state; they must be watery or molten. Electrolysis is the process of dissolving these compounds in a solvent while an electric current is flowing. "Conductance" or "conductor" is the second most crucial word for electrolytic conductance. To gain an understanding of more complex subjects like ... Read More

Introduction The concentration cell is indeed a sort of galvanic cell in which both halves of the cell contain relatively similar electrolytes although with varying concentrations. This is used in association with the electrodes. When obtaining chemical equilibrium, such cells produce a slight voltage difference. These are accomplished by moving electrons from either the lower to the higher concentration cell. Since the electrodes of such a concentration cell seem to be the same, its standard electrode potential becomes 0. However, as the ion concentrations fluctuate, maybe there could be a potential difference between the 2 half-cells. The Nernst Equation may ... Read More

Introduction Electrochemistry is a branch of chemistry that has been introduced by the contributions made by the English chemist John Daniel and the physicist Michael Faraday. John Daniel invented the primary cell and Michael Faraday introduced the laws of electrochemistry. Nernst introduced the electromotive force and put forward an equation that is now known as the Nernst equation. Electrochemistry deals with the study of electron movement. And it also deals with the relationship between electrical and chemical energy. Spontaneous chemical reactions taking place in the electrochemical systems produce a large amount of electrical energy. And the study of this electrical ... Read More

Introduction An electrochemical cell is a system that can generate electrical energy from spontaneous chemical reactions. Lets discuss it further, How does the battery in a mobile phone charge when it is plugged into its charger or how does the cell in a TV remote control function? In the scientific field known as electrochemistry, all these queries have their answers. The study of electrochemistry includes both the use of electricity to conduct non-spontaneous chemical reactions as well as the production of electricity through chemical reactions. Cells are employed to attain the goal. Cells are components that cause chemical reactions that ... Read More

Introduction The name electrode was first put forward by the scientist William Whewell. And is obtained from the Greek word 'Elektron' and 'hodos' which means 'amber' and 'way'. The highly conducting nature of electrodes leads to the use of electrodes in many fields. Electrophore is the early version of an electrode that was discovered by the scientist Johan Wilcke that is used for the study of static electricity. And is also used as a term where the electricity enters or leaves the system. They have become an essential part of batteries and cells after their discovery. Later different types of ... Read More

Introduction Benjamin Franklin during his experiments found that metals can conduct electricity through the lightning experiment. The concept of electrical potential was discovered by Alessandro Volta. The measure of the ability of metals to conduct electricity was put forward by the scientist Georg Simon Ohm. The development in the field of conductors made several advancements in the science field. The conductors are the materials that can conduct electricity and heat by the transfer of these energies from one atom to another. In electrical conductors, the charge carriers such as ions and electrons present in the material will conduct electricity by ... Read More

A battery is a crucial component of any portable electronic device. The battery provides electrical energy required to power the device. It basically performs some chemical reactions to produce electrical electric energy. Batteries are broadly classified into two types namely, rechargeable batteries and non-rechargeable batteries. In this article, we will explore two commonly used types of rechargeable batteries namely, Lithium-Ion (Li-Ion) Battery and Lead Acid Battery and their important differences. The fundamental difference between a lithium-ion battery and a lead acid battery is that a lithium-ion battery uses lithium salt in an organic solvent as the electrolyte, whereas a ... Read More

Introduction The physicist Alessandro Volta discovered first the operable battery by following the studies and experiments done by Luigi Galvani, in 1790. In his study, he focused on the several chemical reactions done by electrochemical cells. By 1800 Alessandro Volta discovered the storage of power or battery. And it consists of alternate layers of Zinc and Silver dipped that are dipped in the brine solution. It was also named volcanic pile and then later Micheal Faraday provided laws of electrochemistry based on this discovery. With the help of these laws, various cells for commercial use have been developed. Later John ... Read More

Introduction The Emf or electromotive force is a term used to depict the potential difference and is not a term related to force and it is measured in volt. It was invented by Alessandro Volta when he first invented the battery. And also he mentioned the contact of electrode and electrolyte is responsible for the emf not mentioned chemical reactions. In 1830 Michael Faraday ascertained that the chemical reactions taking place at the electrode and electrolyte interface are responsible for the emf. It is a characteristic of all the energy sources that have a circuit in them. The electromotive force ... Read More
