Question

Write the mechanism of electrochemical cells that are used in measuring that are used in measuring oxygen and drew the diagram of an electrochemical cell?

Answer 1

Answer:

A simple electrochemical cell can be made from copper and zinc metals with solutions of their sulfates. In the process of the reaction, electrons can be transferred from the zinc to the copper through an electrically conducting path as a useful electric current.
oxidation and reduction reactions are used to provide useful electrical energy in batteries.
An electrochemical cell can be created by placing metallic electrodes into an electrolyte where a chemical reaction either uses or generates an electric current. Electrochemical cells which generate an electric current are called voltaic cells or galvanic cells, and common batteries consist of one or more such cells. In other electrochemical cells an externally supplied electric current is used to drive a chemical reaction which would not occur spontaneously. Such cells are called electrolytic cells.
