Types of Electrodes

Science > Chemistry > Electrochemistry > Types of Electrodes In this article, we shall study different types of electrodes, their representation, writing cell reactions, and finding e.m.f. of a cell. There are four types of electrodes Gas electrodes Metal–sparingly soluble metal salt electrodes Metal – metal ion electrodes Redox Electrodes Gas Electrodes: A gas electrode […]

Reference Electrodes

Science > Chemistry > Electrochemistry > Reference Electrodes The electrode whose potential is arbitrarily fixed or is exactly known at a given constant temperature is known as a reference electrode. Using reference electrodes unknown potential of any other single electrode can be found out e.g. two commonly used reference electrodes are standard hydrogen electrode (SHE) […]

Science > Chemistry > Electrochemistry > Representation of Electrochemical Cell In this article, we shall study the representation of cell using conventions on paper. We shall also discuss the construction and working of the salt bridge. Electrochemical (Voltaic or Galvanic) cell consists of two half cells. In one half-cell, an oxidation reaction takes place and […]

Science > Chemistry > Electrochemistry > Secondary Electrochemical Cells In this article, we shall study the construction and working of lead accumulator, and Ni-Cd cells. Lead Accumulator: A lead accumulator is a secondary cell because electrical energy is not generated within the cell itself but it is previously stored in it from the external source. […]

Types of Cells

Science > Chemistry > Electrochemistry > Types of Cells There are two types of cells: a) Electrolytic cell and b) Electrochemical cells Conversion of Chemical Energy into Electrical Energy: Certain chemical reactions have the capacity to take place spontaneously and can produce electrical energy when carried under appropriate conditions, like proper device, the proper concentration, pressure, […]
