Is Potassium Hydroxide a Reducing Agent in the Reaction with Chlorine?

AI Thread Summary
The reaction of chlorine with hot concentrated potassium hydroxide results in the formation of potassium chloride and potassium chlorate. In this process, potassium hydroxide does not act as a reducing agent; instead, it serves as a medium for the reaction. The oxidation number of chlorine changes from 0 to -1 in the formation of KCl and from 0 to +5 in KClO3. Therefore, the correct statements regarding the reaction are that the oxidation number of chlorine changes from 0 to -1 and from 0 to +5, confirming option D as the correct answer. The discussion clarifies that losing oxygen or hydrogen does not equate to being oxidized or reduced; only electron transfer defines these processes.

The answer is D. But isn't KOH a reducing agent and a oxidizing agent? It loses O and H at the same time.

Losing H or O is in general not equivalent with being oxidized or reduced. The only things that are reduced or oxidized are those that accept or loose electrons.
 
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
