The weight in grams of an element, compound or ion which would react with or replace 1 gram of hydrogen; the molecular weight in grams divided by the valence.
the atomic weight of an element that has the same combining capacity as a given weight of another element; the standard is 8 for oxygen
The system that allows the comparison of papers having different basic sizes and basis weights. For example, 20# bond paper (which has a basic size of 17"x 22") is equivalent to 50# offset (which has a basic size of 17" x 28").
The amount of substance (in grams) that supplies one gram mole of reacting units. The equivalent weight is calculated by dividing the molecular weight of a compound by the change in the oxidation number it experiences during a chemical reaction.
The term used to denote the respective weights of a paper of two different basic sheet sizes.
An oxidizing or reducing agent, who's mass gains (oxidizing agents) or loses (reducing agents) 6.022 x 1023 electrons in a redox reaction. The mass of an acid or base that furnishes or reacts with 6.022 x 1023 H3O+ or OH- ions.
The weight of a material (an element, compound, or ion) that yields (or per) one ionic valence charge. Equivalent weight is computed by dividing the atomic or molecular weight by the valence or number of reactive protons of the substance.
The weight in grams of an element, compound or ion that yields (or per) one ionic valence charge (or one reactive proton).
Equivalent weight is the atomic weight of an element or radical divided by the valence it assumes in a chemical compound. When choosing primary standards in analytical chemistry, compounds with higher equivalent weights are generally more desirable because weighing errors are reduced or minimized.
