ONE FORMULA, ONE ANSWER
Electroplating deposited mass calculator
Use Faraday's law and the entered current efficiency to calculate the mass deposited by the desired electrode reaction. Choose input units and calculate one value within the stated conditions.
Inputs
Calculations run in this browser. Scientific notation such as 1.2e-3 is supported. Do not group thousands.
Result
Deposited mass m
Enter values and select Calculate.
m = η I t M/(zF)
Assumptions
Required: constant current, constant current efficiency and one deposition reaction with a specified electron count. z is the positive integer electron count per deposited formula unit in the balanced electrode reaction. Side reactions are represented by η. Excluded: explicit diffusion limits, redissolution, detachment and changing mass transfer. Plating thickness additionally requires density and actual area.
Displayed values are floating-point approximations. Design safety factors and unprovided error contributions are not calculated.
