Photo voltaic cell converts light energy into electrical energy. It acts as a cell. It consists of a metal layer of copper over which a semiconductor layer of cuprous oxide coated with a thing film of silver or gol..

In order to study the working of an electrolytic cell and the phenomena of electrolysis it is important to know the working of a galvanic or a voltaic cell that generates electrical energy from its chemical reaction. In a simple voltaic cell a zinc ..

Electrodes: Copper (+ve) and Zinc (- ve) Electrolyte: dil. H 2 SO 4 (dilute sulphuric ac..

Electrochemical Cells - The fact that chemical reactions produce electrical effects was discovered accidentally in 1791 by Luigi Galwani, professor of anatomy at the University of Bologna, Italy. He found that an electric current flowed across two dissimilar metals between which was a moi..

In a Daniel cell, in which the concentration of solution may not be 1 M, the cell reaction can be written as: The cell reaction is: In this reaction, the number of electrons released by zinc and accepted by copper ion is same i.e. n = 2 The electrode r..

When one measures the standard electrode potentials, the temperature of the cell is 298 K and the concentration of the electrolyte solutions is fixed as 1 M. However, in actual practice, the electrochemical cells are not always at 298 K nor do always have this con..

. It depends upon the nature of the electrodes and the concentration of the solutions in the two half-cells..
