Mass Deposited vs Time
Fórmula
## 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.
Ejemplo Resuelto
Electroplating copper (M = 63.55, z = 2) with 5 A for 1 hour (3600 s).
- 01m = (I × t × M) / (z × F)
- 02m = (5 × 3600 × 63.55) / (2 × 96485)
- 03m = 1,143,900 / 192,970
- 04m = 5.928 g
Preguntas Frecuentes
What is Faraday's constant?
Faraday's constant (F = 96485 C/mol) is the charge carried by one mole of electrons. It equals the Avogadro number times the elementary charge.
What is the charge number z?
z is the number of electrons transferred per ion. For Cu²⁺ → Cu, z = 2. For Ag⁺ → Ag, z = 1. For Al³⁺ → Al, z = 3.
Can I calculate time needed for a given mass?
Yes, rearrange to t = (m × z × F) / (I × M). This tells you how long to run electrolysis to deposit a target mass.
