Question

What is the difference b/w valence factor & n factor?

Answer 1

The N-factor is generally used as a wider term to describe the relationship between molar mass and equivalent mass.

eg. Molar mass of a substance/ n-factor= equivalent mass of the substance.

It's also used as, normality = molarity * n -factor.

So, the n-factor for an acid is called its basicity, eg. H2SO4, n=2 as it can furnish 2 protons.

Similarly, n-factor for base is its acidity, eg. n-factor for Ca(OH)2 is 2, as it furnishes 2 OH- ions.

For salts, it's the valency eg: Ca2+ as in CaCl2 has n=2

For redox reactions it's the no. Of electrons transferred, KMnO4 (Mn+7) goes to Mn+2 in acidic medium, so it's n-factor is n=5.

Answer 2

Answer:

➡ Valence factor is basically the N-factor of a molecule ...

➡ N-factor is the change in oxidation stare of the molecule in a reaction....
