Question

how to find n factor

Answer 1

Let us have a salt AaBb in which oxidation state of A is +x. It changes to a compound which has atom D in it. The oxidation state of A in AcD is +y. To calculate the n-factor of a salt of such type, we take 1 mol of the reactant and find the number of moles of the element whose oxidation state is changing.

Answer 2

simply.. n-factor is the no. of moles of e- exchanged by 1 mole of substance..
