Question

What is equivalent weight of any substance? i.e define equivalent weight.

Answer 1

The weight of a substance that will combine with or replace one mole of hydrogen or one-half mole of oxygen. The equivalent weight is equal to the atomic weight divided by the valence.

Answer 2

It is not possible to define equivalent mass of a substance in general. It is to be defined for different suv=bstances in a defferent way.

Eq wt of acid = Mol wt / basicity

Eq wt of base = Mol wt /acidity

Eq wt of salt = Mol wt /valency of cation

Eq wt of an element is the weight of the element that combines with or displaces 8 gms of O2, 1.008gm of H2 or 35.5gms of Chlorine.

Answer 3

equivalent wt of a substance can be defined as the molecular wt of the substance divided by acidity or basicity or change in the oxidation number during a reaction

Answer 4

Equivalent weight is the amount of an element that reacts, or is involved in reaction with, 1 mole of electrons. It is 'defined' by many texts as the weight of the element combining with 1 g hydrogen, 8 g oxygen or 35.5 g chlorine, each of which would either provide or accept one mole of electrons in a reaction.

Answer 5

equivalent weight of a substance=molecular weight divided by its valency

Answer 6

1.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

2.
