1. What is the Faraday Constant?

The Faraday constant represents the magnitude of electric charge per mole of electrons. It is a fundamental physical constant denoted by F and has a value of approximately 96,485 coulombs per mole (C/mol).

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( F \) — Faraday constant (C/mol)
• \( Q \) — Electric charge (Coulombs)
• \( n \) — Number of moles (mol)

Explanation: This calculation determines the Faraday constant based on the relationship between electric charge and the number of moles of electrons.

3. Importance of Faraday Constant

Details: The Faraday constant is crucial in electrochemistry for calculating the amount of substance deposited or dissolved during electrolysis. It's used in battery technology, electroplating, and various electrochemical processes.

4. Using the Calculator

Tips: Enter the electric charge in Coulombs and the number of moles. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the exact value of Faraday constant?
A: The accepted value is 96,485.33212... C/mol, though 96,485 C/mol is commonly used for calculations.

Q2: How is Faraday constant related to Avogadro's number?
A: F = Nₐ × e, where Nₐ is Avogadro's number and e is the elementary charge.

Q3: Why is it called Faraday constant?
A: It's named after Michael Faraday, who made significant contributions to electrochemistry.

Q4: What are typical applications of Faraday constant?
A: Used in electroplating, battery capacity calculations, and determining equivalent weights in electrolysis.

Q5: Is Faraday constant the same for all elements?
A: Yes, it's a universal constant that applies to all electrochemical reactions involving electron transfer.
