For acids, n-factor is defined as the number of H+ ions replaced by 1 mole of acid in a reaction. Note that the n-factor for acid is not equal to its basicity; i.e. the number of moles of replaceable H+ atoms present in one mole of acid.
For example, n-factor of HCI = 1,
n-factor of HNO3 = 1,
n-factor of H2SO4 = 1 or 2, depending upon extent of reaction it undergoes.
H2SO4 + NaOH → NaHSO4 + H2O
Although one mole of H2SO4 ahs 2 replaceable H atoms but in this reaction H2SO4 has given only one H+ ion, so its n-factor would be 1.
H2SO4 + 2NaOH → Na2SO4 + 2H2O
The n-factor of H2SO4 in this reaction would be 2.
Similarly,
n-factor of H2SO3 = 1 or 2
n-factor of H2CO3 = 1 or 2
n-factor of H2PO4 = 1 or 2 or 3
n-factor of H3PO3 = 1 or 2 because one of the H is not replaceable in H3PO3. This can be seen using its structure .
The H atoms which are linked to oxygen are replaceable while the H atom linked directly to central atom (P) is nonreplaceable.
