An electrode on whose surface oxidation takes place

Anode

An electrode on whose surface oxidation takes place. anode. In simple terms, an anode is the part of a battery where electricity flows out, and chemical reactions take place.

A device that converts chemical energy to electrical energy, it is made of cells

Battery

A device that converts chemical energy to electrical energy, it is made of cells. Battery. A battery stores energy in chemical form and releases it as electricity when needed.

How much voltage exists between the two half cells of a battery

Cell potential

How much voltage exists between the two half cells of a battery. Cell potential. Cell potential is the measure of the electric potential difference between two half-cells in a galvanic cell, indicating the battery's ability to produce an electric current.

The gradual wearing away of a metal through chemical reactions

Corrosion

The gradual wearing away of a metal through chemical reactions. Corrosion is when metal slowly gets damaged by reacting with the environment, like rust forming on iron.

An electric cell in which the electrolyte is absorbed into a paste, preventing spillage

Dry cell

An electric cell in which the electrolyte is absorbed into a paste, preventing spillage. Dry cell. A dry cell is a type of battery where the liquid electrolyte is minimized into a paste, making it portable and less likely to leak.

A metal strip used to establish electrical contact with a nonmetallic part of a circuit

Electrode

A metal strip used to establish electrical contact with a nonmetallic part of a circuit. Electrode. An electrode is a conductor that allows electricity to flow into or out of a device or material.

The difference in electric potential between an electrode and the electrolyte with which it is in contact

Electrode potential

The difference in electric potential between an electrode and the electrolyte with which it is in contact. Electrode potential. Electrode potential is the voltage difference between a metal electrode and the solution it's in, showing how easily electricity is transferred.

The process in which an electric current is used to produce a chemical reaction

Electrolysis

The process in which an electric current is used to produce a chemical reaction is called electrolysis. Electrolysis is a method where electricity splits substances into their individual components.

An electrochemical device in which electrolysis takes place when an electric current is used

Electrolytic cell

An electrochemical device in which electrolysis takes place when an electric current is used. Electrolytic cell. An electrolytic cell uses electricity to cause a chemical reaction that wouldn't happen on its own.

A process where a coating of metal is added to a conductor using electricity

Electroplating

A process where a coating of metal is added to a conductor using electricity. Electroplating. Electroplating is when a metal layer is deposited onto an object using an electric current.
