1. What is Mass of Substance undergoing Electrolysis Calculator?

Definition: This calculator determines the mass of ions reacted or formed during electrolysis based on the equivalent weight of the substance, current, and time.

Purpose: It helps chemists and electrochemists quantify the amount of substance deposited or liberated during electrolysis.

2. How Does the Calculator Work?

The calculator uses Faraday's law of electrolysis:

Where:

• \( m_{ion} \) — Mass of ions (kilograms)
• \( E \) — Equivalent weight of substance (kg)
• \( I \) — Current (amperes)
• \( t \) — Time (seconds)
• 96485 — Faraday's constant (C/mol)

Explanation: The formula relates the mass of substance deposited at an electrode to the quantity of electricity passed through the electrolyte.

3. Importance of Mass Calculation in Electrolysis

Details: Accurate mass calculations are crucial for industrial electrolytic processes, electroplating, and battery technology development.

4. Using the Calculator

Tips: Enter the equivalent weight in kg, current in amperes, and time in seconds. All values must be > 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 do I find the equivalent weight?
A: Equivalent weight is the molar mass divided by the number of electrons transferred in the reaction.

Q3: What units should I use?
A: Use kilograms for mass, amperes for current, and seconds for time to get results in kilograms.

Q4: Can I use this for any electrolytic reaction?
A: Yes, as long as you know the equivalent weight of the substance involved.

Q5: Why is the result sometimes very small?
A: Electrolysis often deals with small quantities, so results may be in milligrams or micrograms.
