What is Electrolyzed Water?
Electrolyzed water, also known as electrolyzed oxidizing water, is created through a process called electrolysis. This process involves running an electrical current through salt water, splitting it into two distinct solutions at the anode and cathode.
At the anode, the water becomes an acidic solution containing hypochlorous acid (HOCl) – the same compound your white blood cells produce to fight infections. At the cathode, you get an alkaline solution rich in sodium hydroxide (NaOH).
Studies have consistently shown electrolyzed water’s impressive effectiveness. A landmark study by Meakin et al. (2012) found that electrolyzed water significantly outperformed traditional quaternary ammonium disinfectants in reducing bacterial contamination in healthcare settings.
Recent research by Hidayat & Wulandari (2022) further demonstrated that electrolyzed water proved more effective at inactivating viruses than formaldehyde-based disinfectants, while remaining safe for human skin.
The Science Behind Electrolysis of Salt Water
When tap water and salt (sodium chloride) undergo electrolysis in an electrolyzed water generator, a fascinating chemical transformation occurs. The process splits water molecules into hydrogen and oxygen while simultaneously creating two types of water with distinct cleaning capabilities.
Here’s how the electrolysis process works:
At the anode (positive electrode):
Here’s how the electrolysis process works:
At the anode (positive electrode):
- Chloride ions from salt oxidize to form hypochlorous acid (HOCl)
- This creates an acidic solution with powerful disinfectant properties
- The pH typically ranges from 2.5-6.5
- The solution has high oxidation-reduction potential (ORP)
At the cathode (negative electrode):
- Water molecules split, releasing hydrogen gas and forming hydroxide ions
- This creates an alkaline solution effective for cleaning
- The pH typically ranges from 8-11
- Sodium hydroxide (NaOH) forms, excellent for breaking down oils and grease
Research by Chen & Wang (2022) demonstrates that this process creates solutions with remarkable cleaning and disinfecting properties. The acidic electrolyzed water (AEW) proved more effective than conventional sodium hypochlorite and hydrochloric acid in inactivating stubborn pathogens like Staphylococcus aureus.
The Role of Salt in Creating Electrolyzed Water
Salt (sodium chloride) plays a crucial role as the electrolyte in this process. Without salt, the water wouldn’t conduct electricity well enough for effective electrolysis. The salt concentration affects both the production efficiency and the final product’s effectiveness.
For optimal results, studies recommend using pure sodium chloride rather than table salt, as additives might affect the electrolysis process and reduce its efficiency.
How Effective is Electrolyzed Water as a Disinfectant?
