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.

An ideal voltmeter has an infinite resistance, so does not let any current flow in the system. However nothing is ideal in real life, it consumes a very small amount of current to move the magnet and …

I was introduced to this concept using an equilibrium between the metal and its ions. I was then told that those that have a higher tendency to give up electrons will have equilibria lying to t …

My question is that suppose we have to metals, A and B. A produces +1 ions. B produces +2 ions. Now even if the two have the same tendency to lose or gain electrons, the B plate would be 'more …

Quoting your comment A better way to say it maybe that the two form ions just as readily. Then why should electrode B itself not be charged comparatively more negative? Eo is not a direct m …

Think of oxidation in a classical sense for a minute or so. Oxidation is addition of oxygen to a molecule or it can also mean removal of hydrogen. If you carefully look at the structure of ascorbic ac …

It is a bad question because "Metal A is more reactive than Metal B" has no real meaning. It is a vague choice of word, A is more reactive, but with respect to what? Your logic is correct Since A …

Arrow pushing mechanism is just a formal way of thinking how the reaction might be occurring. Unfortunately, organic chemistry textbooks present it as if all of these reactions were occurring in real …

Description of reactions being conducted in "acidic, basic, or neutral medium" are rather qualitative terms which don't add anything until and unless more details are provided. The first clue is that …

You guessed it right that hydrogen and oxygen mixtures will remain stable. Someone in Harvard waited for >30 years and found very little water if any. As you said, there is a energy barrier. What type …

A discharged battery means that cell reaction has achieved equilibrium. When this system is at equilibrium no (useful) work can be done by the battery. It cannot drive or pump electrons in the circuit …
