1. What is Quantity of Charges given Mass of Substance?

Definition: This calculator determines the electric charge required to deposit or liberate a given mass of substance during electrolysis.

Purpose: It helps in electrochemical calculations, particularly in electroplating, battery technology, and industrial electrolysis processes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( q \) — Electric charge (Coulombs)
• \( m_{ion} \) — Mass of ions reacted or formed (kg)
• \( Z \) — Electrochemical equivalent of element (kg/C)

Explanation: The mass of substance is divided by its electrochemical equivalent to determine the charge needed for the electrochemical reaction.

3. Importance of Charge Calculation

Details: Accurate charge calculation ensures proper control of electrochemical processes, efficient material usage, and predictable reaction outcomes.

4. Using the Calculator

Tips: Enter the mass of ions in kilograms and the electrochemical equivalent in kg/C. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is electrochemical equivalent?
A: It's the mass of substance deposited or liberated per unit charge during electrolysis, specific to each element.

Q2: How do I find the electrochemical equivalent?
A: It can be calculated from molar mass and valency, or found in electrochemical reference tables.

Q3: Can this be used for any substance?
A: Yes, as long as you know the electrochemical equivalent of the substance involved.

Q4: What units should I use?
A: Mass in kilograms and electrochemical equivalent in kg/Coulombs for consistent results.

Q5: Does this account for current efficiency?
A: No, this gives theoretical charge. Actual charge needed may be higher due to inefficiencies.
