About Electrolysis

Formula

m = (I × t × MW) / (z × F)

Where F = Faraday's constant (96,485 C/mol)

Key Concepts

  • Faraday's Law: Mass deposited is proportional to charge passed
  • Current (I): Flow of electrical charge per unit time
  • Valence (z): Charge on the ion (e.g., Ag⁺ = 1, Cu²⁺ = 2)
  • Molecular Weight: Mass of one mole of the substance

How to Use

  1. Select the calculation type you want to perform
  2. Enter the required values based on your calculation
  3. Choose appropriate units for current and time
  4. Click Calculate to get the result

Common Applications

  • Electroplating processes
  • Electrorefining of metals
  • Water electrolysis
  • Battery charging/discharging
  • Corrosion studies

Example Values

  • Silver (Ag): MW = 107.87 g/mol, z = 1
  • Copper (Cu): MW = 63.55 g/mol, z = 2
  • Zinc (Zn): MW = 65.38 g/mol, z = 2
  • Aluminum (Al): MW = 26.98 g/mol, z = 3

Important Notes

  • All values must be positive
  • Valence must be a positive integer
  • Units are automatically converted
  • Assumes 100% current efficiency
  • Works for single-ion species
