n-factor can be obtained from the total number of positive charges or total number of negative charges present in potash alum. ... The total negative charges is equal to 8. Thus it can be said that n-factor for potash alum is 8.

Can n factor be zero?

n factor for acids is its basicity,ie, no of replaceable hydrogen ion per molecule. For a base number of OH- ions that a molecule of base could give is n-factor. Therefore, n-factor is zero.

How do you remove N factor?

To calculate n-factor of a salt of such type, we take one mole of the reactant and find the number of mole of the element whose oxidation state is changing. This is multiplied with the oxidation state of the element in the reactant, which gives us the total oxidation state of the element in the reactant.
