what is the difference between a non-reducing and a reducing buffer?

and what does it mean with non-reducing and reducing?

thanks a bunch!

Hi

Havn't done this for a very long time (8-9 years) but I think what you are asking is what is reduction...

some compunds are reducing by nature, this means that they gain electrons from other substances( which are oxidising or losing electrons) for example ferric oxide (FeO) can be oxidised further to ferrous oxide (Fe2O3).

I suggest you look at a basic chemistry text book for oxidation/reduction reactions, they will explain it better than I can off the top of my head and probably tell you examples of oxidising and reducing reactions.

I hope this has helped.
