What is the difference between valence factor and n-factor?

Click For Summary

Discussion Overview

The discussion centers around the concepts of valence factor and n-factor, particularly in the context of oxidants and reductants, using hydrogen peroxide (H2O2) as an example. Participants explore the definitions, applications, and relevance of these terms in chemistry.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant seeks to understand the difference between valence factor and n-factor, specifically for H2O2, and asks how to determine the n-factor for any oxidant or reductant.
  • Several participants express unfamiliarity with the terms "valence factor" and "n-factor," questioning their definitions and origins.
  • Some participants suggest that these terms may be obscure and poorly defined, indicating they are proxies for more established concepts in acid/base chemistry.
  • One participant argues that using these terms in calculations may not be valuable and recommends relying on stoichiometry instead.

Areas of Agreement / Disagreement

Participants generally do not agree on the definitions or relevance of valence factor and n-factor, with multiple competing views on their utility and clarity in the context of chemistry.

Contextual Notes

There is uncertainty regarding the definitions and applications of valence factor and n-factor, as well as their relevance in chemical calculations. Some participants express that these terms may not be widely recognized or used in standard chemistry practice.

What is the difference between valence factor and n-factor for oxidants and reductants? Take ##H_2O_2## as an example. What is the difference between the n-factor and valence factor for this compound?

Also, how do I find the n-factor for any oxidant or reductant?

I am a chemist, and I have never heard of the terms "valence factor" and "n-factor". As you have, where did you hear of them? In class/textbook? What definitions of them were you given?

I've just looked them up on google. So now I know. Couldn't you?

You could have simply said that in this place, I'll not get any answer. I posted this because there was a problem that I was having in understanding the concepts, and no site was able to tell me appropriately the difference between n-factor and valence factor.

If I can't get an answer, it's alright. My teacher is in out station and I was not wanting to disturb him regarding petty issues like these.

If you don't want to answer, then simply write that.

And I can't think of the fact that a chemist doesn't know these simple terms.

I haven't heard about them too. Some googling suggests these are rather obscure terms which are poorly defined proxies for a real chemistry behind acid/base related processes. No wonder you have problems grasping what they really mean.

Yes, they are somehow related to redox reactions and are used to find the equivalent weight.
 
TBH I see no value in using them in calculations. Just follow the stoichiometry and you will get any result you need. Single universal method is typically much better than half-baked proxies.
