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.

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. The equivalent weight of an element is 13.16 . It forms an acidic oxide which with KOH forms a salt isomorphous with K_(2)SO_(4) . The atomic weight of element is:

Equivalent weight of N_(2) and NH_(3) in the change N_(2)rarrNH_(3) respectively is:

"The molecule species having same number of atoms and same total number of valence electrons will have similar molecular orbitals and structures" . This is a statement of

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. One mole of As_(2)S_(3) is oxidised by HNO_(3) to H_(3)AsO_(4) and H_(2)SO_(4).HNO_(3) is converted into NO . The moles of HNO_(3) required are:

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. 20 mL 0.2M MnSO_(4) are completely oxidised by 16 mL of KMnO_(4) of unknown normality each forming Mn^(4+) oxidation state. The normality and molarity of KMnO_(4) are respectively:
