Electrochemistry Flashcards

Vocabulary flashcards based on lecture notes about electrochemistry.

Electromotive Force (emf)

The driving force in a galvanic cell, also known as potential, measured in volts. It is the potential energy difference per unit charge.

Anode

The electrode where oxidation occurs in an electrochemical cell.

Cathode

The electrode where reduction occurs in an electrochemical cell.

Salt Bridge

A component of a galvanic cell that allows ions to transport from one side to another to balance charge.

Electrochemical Cell

A device that uses a redox reaction (RxN) to produce an electromotive force (emf), using the free energy of a reaction.

Cell Notation

A shorthand way to represent an electrochemical cell, showing the anode, cathode, and the solutions they are in.

Standard Hydrogen Electrode (SHE)

A reference electrode used for measuring standard electrode potentials, defined as 0V.

Standard Reduction Potential

The potential of a half-reaction under standard conditions (25°C, 1M, 1 atm) measured against a Standard Hydrogen Electrode (S.H.E.).

Faraday's Constant

The charge of one mole of electrons, approximately 96,485 Coulombs per mole.
