Statement Equivalent weight of a species...

Statement Equivalent weight of a species can be written as molecular weight of species divided by valence factor.
Explanation Valence factor represents valence in element, acidity in bases, basicity in acids and total charge on cation or anion in an ionic compound.

A

`S` is correct but `E` is wrong.

B

`S` is wrong but `E` is wrong.

C

Both `S` and `E` are correct and `E` is correct explanation of `S`.

D

Both `S` and `E` are correct but `E` is not correct explanation of `S.

Text Solution

STATEMENT -1 : Equivalent weight of an acid is always less than its molecular weight. and STATEMENT -2 : Equivalent weight of acid = ("Molecular weight")/("n-factor")

The equivalent weight of a species if acts as oxidant or reductant should be derived by : Eq. weight of oxidant or reductant = ("Mol. wt. of oxidant or reductant")/{("Number of electrons lost or gained by one"),("moleculae of oxidant or reductant"):} During chemical reactions, equal equivalents of one species react with same number of equivalents of other species giving same number of equivalent of products. However this is not true for reactants if they react in terms of moles. Also Molarity can be converted to normality by multiplying the molarity with valence factor or 'n' factor.
