Key answer: H2 has a molar mass of about 2.016 g/mol, diffuses rapidly, has limited water solubility and is chemically stable toward many molecules under ordinary conditions. It is also flammable, so engineering controls and correct operating instructions are essential.
1. Very low molecular mass
Hydrogen is the lightest molecular gas. That helps explain rapid leakage and diffusion, which makes enclosure design, tubing, connections and ventilation important. “Small” should describe a physical property, not be used as automatic proof of a health effect.
2. Fast diffusion
H2 can move through gases, liquids and biological tissues, but actual concentration depends on the source, route and time. In equipment evaluation, leakage control and verified output matter as much as theoretical diffusion.
3. Limited dissolved concentration
Hydrogen-rich water relies on physically dissolved gas. Concentration can fall through headspace, agitation, temperature and time after opening. Buyers should ask for the measurement method, sampling time, container and stated units instead of relying only on electrolysis time or bubbles.
4. Stability and flammability
H2 is relatively non-reactive toward many biological molecules under normal conditions, yet it can burn in air across a broad concentration range. Devices require appropriate gas-path design, ventilation, ignition-source control and clear instructions. Never infer safety from “natural” or “non-toxic” wording alone.
A B2B comparison checklist
Confirm hydrogen-only versus total gas flow, gas composition, water type, electrolysis and membrane configuration, operating pressure, alarms or protective functions, electrical version, consumables, cleaning, warranty and destination-market documentation. Request model-specific evidence rather than generic certificates.
Key points for readers and distributors
- Molar mass and diffusion are physical properties; they do not demonstrate clinical efficacy.
- Dissolved-hydrogen claims require a defined test method and sampling conditions.
- Flammability management is a core product-engineering and user-instruction requirement.

Frequently asked questions
Is pure hydrogen the same as a hydrogen-oxygen mixture?
No. Composition, flow reporting and safety considerations differ.
Can bubble volume prove dissolved hydrogen concentration?
No. Dissolved concentration must be measured with an appropriate method under stated conditions.
