Lesson Flashcards: Galvanic Cells Chemistry

Electrode

A conductor used to transfer electrical current to and from a nonmetallic part of a circuit

Cathode

The electrode at which reduction occurs

Galvanic cell

A type of electrochemical cell where electrons are generated spontaneously through a redox reaction and pass through an external circuit

Electrolytic cell

An electrochemical cell that uses electrical energy to drive a nonspontaneous chemical reaction

Half-cell

A system composed of a conductive electrode in an electrolyte solution

Anode

The electrode at which oxidation occurs

Electrochemical cell

A system or device that converts chemical energy to electrical energy or electrical energy to chemical energy

Standard hydrogen electrode

A reference electrode against which all other electrode reduction potentials are measured

Salt bridge

A tube containing an electrolyte connecting two half-cell solutions and providing electrical contact, thereby completing a circuit
