1. What is Current Flowing given Mass and Equivalent Weight?

Definition: This calculator determines the electric current flowing during electrolysis based on the mass of ions reacted, their equivalent weight, and the time duration.

Purpose: It helps chemists and electrochemists calculate the current required or produced in electrochemical reactions.

2. How Does the Calculator Work?

The calculator uses Faraday's law of electrolysis:

Where:

• \( I \) — Current (Amperes)
• \( m_{ion} \) — Mass of ions reacted/formed (kg)
• \( E \) — Equivalent weight of substance (kg)
• \( t \) — Total time of electrolysis (seconds)
• 96485 — Faraday's constant (C/mol)

Explanation: The formula relates the quantity of substance transformed at an electrode to the quantity of electricity used.

3. Importance of Current Calculation in Electrolysis

Details: Accurate current calculation is essential for controlling electrochemical processes, determining reaction rates, and predicting product yields.

4. Using the Calculator

Tips: Enter the mass of ions in kg, equivalent weight in kg, and total 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 determine equivalent weight?
A: Equivalent weight is the molecular weight divided by the number of electrons transferred per molecule in the reaction.

Q3: Why is time important in this calculation?
A: Current is the rate of charge flow, so longer times with the same mass reaction result in lower current values.

Q4: Can this be used for any electrochemical reaction?
A: Yes, as long as you know the mass change, equivalent weight, and time duration.

Q5: What units should I use?
A: Use kilograms for mass and equivalent weight, and seconds for time to get current in amperes.
