Difference between Galvanic Cell and Electrolytic Cell

Electrical Academia. A galvanic cell is the one in which an oxidation-reduction chemical reaction occurs spontaneously to generate electrical energy. Chemical energy is converted into electrical energy. An electrolytic cell is the one in which electrolysis process takes place, a chemical compound is disintegrated by passing electricity through it.

The chemical reaction taking place is not self-generated spontaneous , it is forced by employing a voltage. The two cells also differ considerably with regard to the electric charges on the electrodes. For instance, in galvanic cell anode is negative while in an electrolytic cell, the anode has a positive charge. Likewise, the cathode is positive in an electrochemical cell , the cathode has negative charge whilst it is negative in the electrolytic cell.

In electrochemistry, oxidation and reduction chemical reaction play a crucial part. In such chemical reactions, electrons are being transferred from one reactant to another.

The element that takes electrons is called a reducing agent, whereas the element that leaves the electron is recognized as the oxidizing agent. The reducing agent is accountable to reduce the other reactant whilst experiencing oxidation itself. And for oxidizing agent , it is vice versa. Such chemical reactions can be separated into two half-reactions, to demonstrate separate oxidations and reductions. Chemical reaction Chemical reaction is forced by applying a certain voltage NOT spontaneous Chemical reaction is spontaneous Electrons Supply Electrons are supplied to the cell from an external source Electron are drawn from the cell Uses Electroplating and purifying Copper Batteries.

But they are not the only kind of electrochemical cell. The reverse reaction in each case is non-spontaneous and requires electrical energy to occur. Introduction.
