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..

(Pt), H 2 (g, 1 atm) H + (aq) (1 mol L -1 ) Cu 2+ (ag) (1 mol L -1 ) Cu(s) at 298 K is called the standard electrode potential of cupric ion - copper electrode denotes as The EMF of the cell is:..

Standard cell - The electrodes used in the cells discussed so far, deteriorate with the passage of current and cannot offer a constant emf indefinitely. However, there was a few cells called standard cells, which can maintain a fairly co..

Calculation of Cell Potential - In an electrochemical cell, electrons flow from negative electrode to the positive electrode. This shows that there is a potential difference between the two electrodes. The minimum potential which causes the flow of the electrons from the negativ..
