|
ph scale
(pH, pH scale)
Princeton's WordNet
(from potential of Hydrogen) the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter; provides a measure on a scale from 0 to 14 of the acidity or alkalinity of a solution (where 7 is neutral and greater than 7 is more basic and less than 7 is more acidic);

|
equivalence
Webster Dictionary
the quantity of the combining power of an atom, expressed in hydrogen units; the number of hydrogen atoms can combine with, or be exchanged for; valency. See Valence
|
tritium
(tritium)
Princeton's WordNet
a radioactive isotope of hydrogen; atoms of tritium have three times the mass of ordinary hydrogen atoms
|
hydrosulphide
Webster Dictionary
one of a series of compounds, derived from hydrogen sulphide by the replacement of half its hydrogen by a base or basic radical; as, potassium hydrosulphide, KSH. The hydrosulphides are analogous to the hydrates and include the mercaptans
|
microcrith
Webster Dictionary
the weight of the half hydrogen molecule, or of the hydrogen atom, taken as the standard in comparing the atomic weights of the elements; thus, an atom of oxygen weighs sixteen microcriths. See Crith
|
sulphydrate
Webster Dictionary
a compound, analogous to a hydrate, regarded as a salt of sulphydric acid, or as a derivative of hydrogen sulphide in which one half of the hydrogen is replaced by a base (as potassium sulphydrate, KSH), or as a hydrate in which the oxygen has been wholly or partially replaced by sulphur
|
hydrogenous
Webster Dictionary
of or pertaining to hydrogen; containing hydrogen
|
valence
Webster Dictionary
the degree of combining power of an atom (or radical) as shown by the number of atoms of hydrogen (or of other monads, as chlorine, sodium, etc.) with which it will combine, or for which it can be substituted, or with which it can be compared; thus, an atom of hydrogen is a monad, and has a valence of one; the atoms of oxygen, nitrogen, and carbon are respectively dyads, triads, and tetrads, and have a valence respectively of two, three, and four
|
equivalent
Webster Dictionary
that comparative quantity by weight of an element which possesses the same chemical value as other elements, as determined by actual experiment and reference to the same standard. Specifically: (a) The comparative proportions by which one element replaces another in any particular compound; thus, as zinc replaces hydrogen in hydrochloric acid, their equivalents are 32.5 and 1. (b) The combining proportion by weight of a substance, or the number expressing this proportion, in any particular compound; as, the equivalents of hydrogen and oxygen in water are respectively 1 and 8, and in hydric dioxide 1 and 16
