how to find the n-factor of a compund???

pls xplain clearly..

n-factor is defined as the total change in oxidation number per mole of the substance .

take an example :

 CuCN -----------> Cu⁺²  +  CO₂  +  HNO₃

          (A) 11

          (B) 7

          (C) 9

          (D) 3

Here , Cu⁺ is converted to Cu^{2+ _.}

There is no change in oxidation number for C ( it remains as +4 )

N is converted from -5 to +5 state .

So the net change in oxidation number , n-factor = (2-1) + [5-(-5)]  

                                                                       =11 .

So Answer is (A.)

so now try solving this question.

calculate n factor of HCuCl₂ in
2HCuCl₂ → Cu + Cu²⁺ + 4Cl^-+ 2H⁺

Hope that helps , Please approve

thnx alot........
