Electroplating Simulator — Faraday's Laws of Electrolysis

Electroplating uses an external electric current to force metal ions in solution to reduce and deposit onto a cathode — the reverse of the spontaneous reactions in a galvanic cell. This 2D simulator applies Faraday's laws (m = ηMIt/nF) to five common plating metals, letting you set current, cathode area and current efficiency while a cross-section of the plating bath fills with a visibly growing coating layer on the cathode, and reads out elapsed time, charge passed, deposited mass and coating thickness in real time on live mass-vs-time and thickness-vs-time charts — the same numbers an electroplating shop uses to time a chromium, silver, nickel, copper or zinc coating to a target micron thickness.
