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 > 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. […]
