What is an Electrochemical Reaction? ;
An electrochemical reaction is a process that involves the transfer of electrons between two substances. The electrons are transferred through a conductor, such as a wire, to create an electrical current. Electrochemical Reaction – Applications.
The Process of Electrochemical Reaction
The process of an electrochemical reaction is the transfer of electrons between two substances. In an electrochemical reaction, one substance, called the anode, transfers electrons to another substance, called the cathode. The anode and cathode are usually two different metals that are in contact with each other. The anode is the metal that loses electrons, and the cathode is the metal that gains electrons.
Application of Electrochemical Cell
An electrochemical cell is a device that uses a chemical reaction to produce an electric current. The most common type of electrochemical cell is the battery. Electrochemical cells are also used in fuel cells and electroplating.
The anode is the negative electrode and the cathode is the positive electrode.
When the battery is connected to a circuit, the electrons flow from the anode to the cathode. This creates a current in the circuit.
