Question

why we used n-factor in redox titration not in acid base titration?​

Answer 1

Answer:

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. ... n-factor of H3PO3 = 1 or 2 because one of the H is not replaceable in H3PO3
