Equivalent Weight

Name:
Equivalent Weight
Detailed information:
(combining weight). The weight of an element that combines chemically with 8 g of oxygen or its equivalent. Since 8 g of oxygen combines with 1.008 g of hydrogen, the latter is considered equivalent to 8 g of oxygen. When 8 g is selected for the combining weight of oxygen, no element has a combining-weight value greater than one. The equivalent weight of an acid is the weight that contains one atomic weight of acidic hydrogen, i.e., hydrogen that reacts during neutralization of acid with base. The equivalent weight of a base or hydroxide is the weight that will react with an equivalent weight of acid. Equivalent weights of other substances are defined in a similar manner.
