Questions tagged [redox]
Redox is the portmanteau of reduction and oxidation. This tag should be used in questions where both the reduction and the oxidation process are under focus. This tag is not limited to inorganic chemistry. If the question is specifically about either reduction or oxidation (not both) of an organic compound, use [organic-reduction] or [organic-oxidation] instead.

Oxidation of Toluene with Permanganate in Acidic and Basic Environment
So, in my current undergrad organic chemistry course, we were introduced to oxidation using permanganate. I know that alkenes can be oxidised to carbonyl compounds using hot, acidic KMnO4, but in our ...

Correct interpretation of Impedance: IR-Drop and Nyquist plots
Good day guys,
I have been lately studying impedance and IR drop in electrochemical systems.
From my readings I have come across different interpretations.
According to my books, from the Nyquist plot:...

Nitrogen fixation
As of today (2024.06.20), Wikipedia tells:
Nitrogen fixation is a chemical process by which molecular dinitrogen ($\ce{N2}$) is converted into ammonia ($\ce{NH3}$)
Obviously, this is only half of ...
