1. What is Electrochemical Equivalent?

Definition: The electrochemical equivalent of an element is the mass of that element (in grams) transported by 1 coulomb of electric charge.

Purpose: It's a fundamental concept in electrochemistry that helps quantify the relationship between electrical charge and chemical change during electrolysis.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Z \) — Electrochemical equivalent (kg/C)
• \( E \) — Equivalent weight of substance (kg)
• \( 96485 \) — Faraday's constant (C/mol)

Explanation: The equivalent weight is divided by Faraday's constant to determine how much mass is deposited or dissolved per unit charge.

3. Importance of Electrochemical Equivalent

Details: This value is crucial for designing electrochemical cells, calculating deposition rates in electroplating, and determining battery capacities.

4. Using the Calculator

Tips: Enter the equivalent weight of the substance in kilograms. The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What is Faraday's constant?
A: Faraday's constant (96485 C/mol) represents the electric charge carried by one mole of electrons.

Q2: How is equivalent weight determined?
A: Equivalent weight is calculated as the molar mass divided by the number of electrons transferred in the reaction.

Q3: Why is this calculation important in industry?
A: It's essential for processes like electroplating, metal refining, and battery manufacturing where precise material deposition is critical.

Q4: What units should I use?
A: The calculator uses kilograms for weight and kilograms per coulomb for the result, but you can convert to grams if needed.

Q5: Can this be used for all elements?
A: Yes, but you must know the correct equivalent weight for the element's specific oxidation state in the reaction.
