Electrochemistry is that branch of chemistry which deals with the relationship between chemical energy and electrical energy. Chemical reactions produce electrical energy and conversely, electrical energy can carry out chemical reactions. These transformations take place through the flow of electrons . Electrons are evolved at one place (oxidation), transferred through a conductor (metal wire) and absorbed at another place (reduction). A chemical reaction can generate electrical energy if it takes place

Unformatted text preview: spontaneously, when carried out under appropriate conditions. Here conditions mean proper device, concentration and temperature or pressure. The reaction of zinc with copper sulfate is one such example which produces heat energy when reacted upon in a simple vessel. But when the same reaction is carried out in a special device called Daniell cell it produces electrical energy....
