Hello everyone, I've been reading up on electrochemistry and trying to make the connection from chemistry theory to what I learned during my time as an undergrad and grad student in electrical engineering and I'm having trouble bridging the gap. I have selected one example from my reference text that I'm hoping someone can better help me explain.
An aqueous solution of CuSO4 was electrolyzed between inert electrodes for 30 minutes. The only cathode reaction was the deposition of 0.231 g of Cu.
Okay, just interpreting that part, I believe that since the cathode reaction only involved Cu, that the SO42- ion wasn't affected by the electrolysis.
The book then says that the "reaction of the anode" can then be determined, and at the anode, a gaseous product evolves.
1. Can anyone describe what they mean by the reaction at the anode can be determined? What is it? How does one find it?
2. For the gaseous product that evolves at the anode, can we calculate it?
2.a - If so, can we calculate it in terms of its mass, volume, and chemical moles?
Thank you! I really appreciate any and all help! - Brim
