What is a Battery? A Battery is a device consisting of one or more electrical cells that convert chemical energy into electrical energy. Every battery is basically a galvanic cell where redox reactions take place between two electrodes which act as the source of the chemical energy. Battery types Batteries can be broadly divided into two major…

What is an Electrolytic Cell? An electrolytic cell can be defined as an electrochemical device that uses electrical energy to facilitate a non-spontaneous redox reaction. Electrolytic cells are electrochemical cells that can be used for the electrolysis of certain compounds. For example, water can be subjected to electrolysis (with the help of an electrolytic cell) to form…

We know that metals are good conductors of electricity as they have a pool of free electrons that flow under the influence of a potential gradient and cause the electric current. But what do we mean by electrolytic conductance? To understand electrolytic conductance, let us first understand electrolytes. Electrolytes are those substances that dissolve in a…

What is Nernst Equation? The Nernst equation provides a relation between the cell potential of an electrochemical cell, the standard cell potential, temperature, and the reaction quotient. Even under non-standard conditions, the cell potentials of electrochemical cells can be determined with the help of the Nernst equation. The Nernst equation is often used to calculate the…

What is Galvanic Cell? An electrochemical cell that converts the chemical energy of spontaneous redox reactions into electrical energy is known as a galvanic cell or a voltaic cell. Galvanic cell Voltaic cell is an electrochemical cell that makes use of chemical reactions to generate electrical energy. Let us understand how a voltaic or galvanic cell is created.…

An electrochemical cell is a device capable of either generating electrical energy from chemical reactions or using electrical energy to cause chemical reactions. What is an Electrochemical Cell? An electrochemical cell is a device that can generate electrical energy from the chemical reactions occurring in it, or use the electrical energy supplied to it to…
