  1. Equivalent

    The equivalent, sometimes termed the molar equivalent, is a unit of amount of substance used in chemistry and the biological sciences. The equivalent is formally defined as the amount of a substance which will either: ⁕react with or supply one mole of hydrogen ions in an acid–base reaction; or ⁕react with or supply one mole of electrons in a redox reaction. The mass of one equivalent of a substance is called its equivalent weight. A historical definition, used especially for the chemical elements, describes an equivalent as the amount of a substance that will react with one gram of hydrogen, or with eight grams of oxygen, or with 35.5 grams of chlorine, or displaces any of the three. In practice, the amount of a substance in equivalents often has a very small magnitude, so it is frequently described in terms of milliequivalents, the prefix milli denoting that the measure is divided by 1000. Very often, the measure is used in terms of milliequivalents of solute per litre of solvent. This is especially common for measurement of compounds in biological fluids; for instance, the healthy level of potassium in the blood of a human is defined between 3.5 and 5.0 mEq/L.
