Faraday's Law of Electrolysis

Formula

m = (I × t × M) / (z × F)

Where:

  • m = mass deposited (g)
  • I = current (A)
  • t = time (s)
  • M = molar mass (g/mol)
  • z = charge number (electrons per ion)
  • F = 96485 C/mol (Faraday's constant)

    • The mass deposited is proportional to the charge passed and the molar mass, and inversely proportional to the charge number.

    计算示例

    Electroplating copper (M = 63.55, z = 2) with 5 A for 1 hour (3600 s).

    1. m = (I × t × M) / (z × F)
    2. m = (5 × 3600 × 63.55) / (2 × 96485)
    3. m = 1,143,900 / 192,970
    4. m = 5.928 g
