Question

how can we find valency factor of an ęĺęměňț????


Pls ans only if u know​

Answer 1

Answer:

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.

Explanation:

Suppose I am given some reaction in which

C6H12O6⟶CO2

and I want to calculate n-factor for this reaction to ultimately calculate equivalent weight of carbon for this reaction. Since

E=Mn

I know that n-factor is no of electron gained/lost by one atom of a compound.

So Initial Oxidation state of carbon is

6x+12−12=0

x=0

meaning and final oxidation state of carbon is

−4

Hence, n-factor of this reaction should be 4 but it's given to be 28
