Why Does Electrical Purification of Copper Involve Both Oxidation and Reduction?

AI Thread Summary
The electrical purification of copper involves both oxidation and reduction processes, utilizing an anode and a cathode. Impure copper is placed at the anode, where it undergoes oxidation, releasing copper ions into the solution. At the cathode, copper ions are reduced and deposit as pure copper. This dual process is essential for effectively separating impurities from the copper. Understanding these reactions is crucial for grasping the principles of electrolysis in metal purification.

Why the electrical purification of copper involves both an oxidation and a reduction process.
 
Physics news on Phys.org
You understand that the electrical purification requires both an anode and a cathode. Can you explain where the impure copper goes (anode or cathode) and what reaction is taking place there?

Yeah I guess it does look like a bit like homework, I'll edit the answer. :o

Posts like this where there's almost no effort on the part of the user to elaborate on any aspect of the question are usually suspect.

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

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...
