Equivalent weight of a compound
The valence factor of a compound depends on the manner a compound is involved in a reaction. The compounds of alkali metal salts and alkaline earth metal salts are, however, constant. These compounds are ionic and they dissociate in ionic components in aqueous solution. In this case, valence factor is equal to numbers of electronic charge on either cation or anion.
Equivalent weight,E=
Molecular weight of compoundNumbers of electronic charge on cation or anion
The numbers of electronic charge on cation ofNaHCO3 is 1. Hence, equivalent weight ofNaHCO3 is (23 + 1 + 12 + 3X16)/1 = 84.
If we look at the defining ratio of equivalent weight of a compound (AB) formed of two radicals (say A and B), then we can rearrange the ratio as :
Equivalent weight, E=
Molecular weight of Radical ANumbers of electronic charge +Molecular weight of Radical BNumbers of electronic charge
Thus,
⇒Equivalent weight of AB=Equivalent weight of A+Equivalent weight of B
