 What is Faraday Constant? In physics as well as in Chemistry, Faraday represents the magnitude of electric charge per mole of the electron. Faraday is equivalent to the Faraday constant. Denoted by the symbol F. The constant was named after Michael Faraday. It has got plenty of applications in electrolysis.

It has currently universally accepted value

Faraday constant (F) =96485.33289(59) C mol−1

### Other Common Units

Value of Faraday constant can be expressed using other units as follows,

 Equivalent value Units 96485 Joule per volt gram equivalent 23.061 kcal per volt gram equivalent 26.801 A·h/mol

This constant can be expressed in terms of two other physical constants as-

F = eNA
Where,

• e is the charge of the electron in coulombs e = 1.60217662×10−19 C
• NA is the Avogadro constant. NA = 6.022141×1023 mol−1.

## Applications

One of the most common uses of Faraday constant is in electrolysis. Dividing the amount of charge in coulombs by the Faraday constant gives the amount in moles of elements that have been oxidized.

## Calculation

Researches have been carrying out till today to increase the accuracy of Faraday constant. Although it was initially determined using Faraday’s law of electrolysis. In general, for an electrochemical reaction, a measured value of current is made to pass for a certain time and the value of F was calculated by measuring the amount of silver deposited.
