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 during electrolysis.

Purpose: This calculator helps determine how much substance is deposited or dissolved per unit charge in electrochemical processes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Z \) — Electrochemical equivalent (kg/C)
• \( m_{ion} \) — Mass of ions reacted or formed (kg)
• \( i \) — Electric current (A)
• \( t \) — Total time taken (s)

Explanation: The mass of substance deposited or dissolved is divided by the total charge passed (current × time).

3. Importance of Electrochemical Equivalent

Details: This value is crucial in electroplating, battery technology, and industrial electrolysis processes for accurate material deposition calculations.

4. Using the Calculator

Tips: Enter the mass of ions in kilograms, electric current in amperes, and total time in seconds. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are typical units for electrochemical equivalent?
A: While SI units are kg/C, it's often expressed in g/C or mg/C for practical applications.

Q2: How does temperature affect the result?
A: The electrochemical equivalent is a fundamental property and doesn't vary with temperature, though reaction rates might.

Q3: Can this be used for any substance?
A: Yes, but the substance must participate in the electrochemical reaction (either as reactant or product).

Q4: What's the relationship with Faraday's laws?
A: The electrochemical equivalent is related to molar mass and Faraday constant (Z = M/nF).

Q5: Why might my experimental values differ?
A: Differences can occur due to side reactions, current inefficiencies, or measurement errors in mass or current.
