How to Use This Calculator

Enter the values of current, time, molar mass, and number of electrons involved in the redox reaction. The calculator will automatically compute the mass of the substance deposited or liberated during electrolysis.

What is This Calculator Used For?

This Electrolysis Calculator helps in determining the mass of a substance deposited on an electrode during electrolysis. It uses Faraday's laws of electrolysis.

Formula

Mass = (It × M) / (n × F)

Where:

• I = Current (A)
• t = Time (s)
• M = Molar Mass (g/mol)
• n = Number of electrons
• F = Faraday Constant (96485 C/mol)

Example

If 2.5 A of current flows for 1800 seconds and copper (M = 63.5 g/mol) is deposited with 2 electrons involved:

Mass = (2.5 × 1800 × 63.5) / (2 × 96485) ≈ 1.48 g
