Mass of Ions Formula:
From: | To: |
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.
The calculator uses Faraday's law of electrolysis:
Where:
Explanation: The formula relates the mass of substance deposited at an electrode to the quantity of electricity passed through the electrolyte.
Details: Accurate mass calculations are crucial for industrial electrolytic processes, electroplating, and battery technology development.
Tips: Enter the equivalent weight in kg, current in amperes, and time in seconds. All values must be > 0.
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.
