  Negative Hydrogen Ion Site: H-minus Ion As a Stable Entity at STP and in Biophysics
The negative hydrogen ion, also called the hydride ion, was until recently considered to be primarily the province of plasma physicists.
The H-minus ion (another name for this ion) has, in the past ten years, been found to be quite plentiful in the earth's interior and even on the surface of the earth.
The H- ion has been noted to be relatively fragile when stored in both water and biological systems, and much of the content of atomic H and the H- ion of plant and animal tissue disappears upon consistent heating, as might be applied when humans cook and prepare plant and animal foods.

  OMEGA ENGINEERING - Intro to pH
Since the relationship between hydrogen ions and hydroxyl ions in a given solution is constant for a given set of conditions, either one can be determined by knowing the other.
Since the atomic weight of the hydrogen ion (H+) is one (1), there is one gram of hydrogen ions in a mole of hydrogen.
The pH measuring electrode is a hydrogen ion sensitive glass bulb, with a millivolt output that varies with the changes in the relative hydrogen ion concentration inside and outside of the bulb.

  Hydrogen - Wikipedia, the free encyclopedia
Hydrogen (Latin: 'hydrogenium', from Ancient Greek: hydro: "water" and genes: "forming") is a chemical element in the periodic table that has the symbol H and atomic number 1.
Hydrogen forms hydrides with all main group elements with the exception of the noble gases and indium and thallium.
Deuterium, an isotope of hydrogen (hydrogen-2), is used in nuclear fission applications as a moderator to slow neutrons, and in nuclear fusion reactions.

 Hydrogen fluoride (PIM 268)
The effect is primarily mediated by the toxicity of the fluoride ion rather than the effect of the hydrogen ion.
The fluoride ion is the most electronegative element in the periodic table; it is a relatively small ion and therefore diffuses readily; and, because hydrogen fluoride is a weak acid, there are sufficiently uncharged species to allow tissue penetration.
Absorption of the fluoride ion is a significant hazard mainly due to hypocalcaemia.

 Hydrogen Embrittlement
Hydrogen is often a byproduct of corrosion and electrochemical processes in aqueous solutions.
In aqueous environments, atomic hydrogen results from the donation of a proton to a hydrogen ion to form atomic hydrogen on the surface of the material.
The effects of hydrogen on cracking are contrasted to those of local metallic dissolution in Fig.

hydrogen ion definition - Dictionary - MSN Encarta
positively charged ion of hydrogen: a positively charged ion of hydrogen that is formed by the removal of an electron from a hydrogen atom and is present in solutions of acids in water.
The degree to which a compound produces hydrogen ions in solution is measured on the pH scale, 1 being highly acidic, 7 being neutral, and 14 being highly alkaline.

 Acid-Base Equilibria
(aq), depicts the hydrogen ion as being held by a molecule of water.
ions: (a) decrease due to an increase of negative charge on the central atom; (b) decrease due to the fewer number of remaining H+ atoms; (c) remain fairly constant; (d) increase due to the increasing polarity of the 0-H bonds; (e) increase due to repulsions between the H+ ions.
The conjugate base of an acid: (a) is the molecule or ion left after the acid accepts a proton; (b) is not stable under most conditions; (c) is a stronger acid than the original acid; (d) is the molecule or ion left after the acid donates a proton; (e) cannot itself be an acid.

 Hydrogen Chloride
It should be noted that the Hydrogen Ion, H(+), is stabilised by hydration in aqueous solution, as the Hydronium Ion, H3O(+).
Hydrogen Chloride gas is very soluble in water, and a solution of the gas forms Hydrochloric Acid.
Hydrogen Chloride may be prepared in the laboratory by heating Concentrated Sulphuric Acid, with Sodium Chloride.

 complex ions - acidity of the aqua ions
The complex ion is acting as an acid by donating a hydrogen ion to water molecules in the solution.
If you have ions of the same charge, it seems reasonable that the smaller the volume this charge is packed into, the greater the distorting effect on the electrons in the O-H bonds.
Ions with the same charge but in a smaller volume (a higher charge density) would be expected to be more acidic.

 Acid Base Balance (page 1)
The hydrogen ion consists of a single positively charged particle (the proton) that is not orbited by any electrons.
The hydrogen ion is, therefore, the smallest ionic particle and is extremely reactive.
Similarly, as hydrogen ions are removed from solution by addition of a strong base the reaction moves to the right restoring the hydrogen ion concentration and reducing the quantity of HA.

 Acids and Bases
Arrhenius suggested that acids are compounds that contain hydrogen and can dissolve in water to release hydrogen ions into solution.
ion, hydrogen minus its electron, is simply a proton).
Under the Brønsted-Lowry definition, both acids and bases are related to the concentration of hydrogen ions present.  Acids increase the concentration of hydrogen ions, while bases decrease the concentration of hydrogen ions (by accepting them).  The acidity or basicity of something therefore can be measured by its hydrogen ion concentration.

 Etherington & Roberts. Dictionary--hydrogen-ion concentration   (Site not responding. Last check: )
The hydrogen-ion concentration of a solution may also be expressed in terms of its pH, which is defined as the negative logarithm to the base ten of the hydrogen-ion concentration.
In aqueous solutions, neutrality is the condition that exists when the concentration of hydrogen ions and hydroxyl ions are equal.
Measurement of hydrogen-ion concentration, or pH, may be made colorimetrically, by means of the proper use of suitable neutralization indicators, or, more accurately, by potentiometric methods employing any of various electrodes, which exhibit the proper specificity for hydrogen ions.
