Basic Chemistry for Understanding Molecular Hydrogen

Articles from the Molecular Hydrogen Institute on Basic Chemistry for Understanding Molecular Hydrogen.

Calculating The Dose Of H2

If the concentration is given in ppm, first convert the ppm to mg/L. Then, multiply the volume of water (in liters) by the concentration (in mg/L) to calculate the amount of H2 which will be ingested (in mg). When considering ingested amounts, not only the concentration, but also the volume of ingested water must be considered. This is because it takes fewer milligrams of H2 to produce 1 ppm in a smaller amount of water than it does in a larger volume of water.

Concentration and Solubility of H2

The concentration of hydrogen gas (H2) is often reported in molarity (moles/liter (M) or milimoles/L mM), parts per million (ppm), parts per billion (ppb) or miligrams per liter (mg/L).

Dissolved Hydrogen Versus Undissolved Hydrogen

The manner in which hydrogen gas is dissolved in the water has an effect on its stability and rate of exsolution (coming out of solution) and dissipation. Hydrogen gas can exist in water as fully dissolved gaseous solutes, colloidal and suspension forms, as well as large macrobubbles that exit almost immediately.

Dummies Guide To Hydrogen

Hydrogen is the lightest and simplest element with the symbol H. It consists of only one electron and one proton and, under normal conditions, it exists primarily in its diatomic form as molecular hydrogen (H2 gas).

Water: A Molecule Of Life

Water is the universal solvent;1 it can exist as a solid, liquid or gas.2 It is necessary for the functions of life3 and for life to function.4 Water is the life-giving fluid that is always at the heart of creation.5 Its presence supports life, and its absence brings death.6 Water in liquid state is the principle criteria for planetary habitability.7

Common Myths about pH

One of the important parameters of water quality is the pH.1 A pH measurement reveals whether the solution is acidic, neutral, or alkaline. The chemistry of water has been discussed previously, which will help us understand what pH really is.
