Understanding Electrolysis and Faraday's Laws
What is Electrolysis?
Electrolysis is a chemical process that uses electric current to drive non-spontaneous chemical reactions. It involves the decomposition of electrolytes (substances that conduct electricity when dissolved) by passing electric current through them.
Key Components
- •Electrodes: Conductors where oxidation and reduction occur
- •Electrolyte: Ionic solution that conducts electricity
- •External Current: Power source driving the reaction
Faraday's Laws of Electrolysis
First Law
m = Z × Q
m = Mass deposited (kg)
Z = Electrochemical constant (kg/C)
Q = Electric charge (C)
Charge Calculation
Q = I × t
I = Current (A)
t = Time (s)
Q = Charge (C)
Industrial Applications
Electroplating
Coating objects with thin layers of metal for corrosion protection, decoration, or improved properties.
Hydrogen Production
Water electrolysis for clean hydrogen fuel generation, essential for sustainable energy systems.
Metal Refining
Purification of metals like copper, aluminum, and zinc through electrochemical processes.
Example: Copper Electroplating
Process Setup
Current: 2.0 A
Time: 30 minutes (1800 s)
Element: Copper (Z = 3.295×10⁻⁷ kg/C)
Mass Calculation
Q = I × t = 2.0 A × 1800 s = 3600 C
m = Z × Q = 3.295×10⁻⁷ kg/C × 3600 C
m = 1.186×10⁻³ kg = 1.186 g copper deposited
