Mass Deposited vs Total Charge (Q)
Formula
## Mass from Charge in Electrolysis ### Formula **m = (Q × M) / (z × F)** Where: - **m** = mass deposited (g) - **Q** = total charge passed (C) = I × t - **M** = molar mass (g/mol) - **z** = charge number - **F** = 96485 C/mol This is Faraday's Law expressed in terms of total charge rather than current and time.
Esempio Risolto
Pass 18,000 C through a silver nitrate solution (M = 107.87, z = 1).
- 01m = (Q × M) / (z × F)
- 02m = (18000 × 107.87) / (1 × 96485)
- 03m = 1,941,660 / 96485
- 04m = 20.124 g of silver
Domande Frequenti
How do I find the total charge?
Q = I × t, where I is current in amperes and t is time in seconds. For example, 5 A for 1 hour = 5 × 3600 = 18000 C.
What metals can be electroplated?
Common electroplated metals include silver (z=1), copper (z=2), nickel (z=2), chromium (z=3), gold (z=1 or 3), and zinc (z=2).
What happens at the other electrode?
If a metal is deposited at the cathode, oxidation occurs at the anode. This could dissolve the anode metal or produce gas (e.g., O₂ from water).
