I really hope someone can help me solve this thing because it's really making my head hurt
Ok so first let's assume I am not very good at electrochemistry
. I have this situation:
I am setting up a galvanic system to monitor pH changes.
I have a carbon rod and a copper wire, each one in a beaker with a salt bridge to connect them.
They are connected to a battery this way: carbon rod
to RED wire and copper
to BLACK wire.
I turn the battery on and the solution with the carbon rod
turns ACIDIC and the one with the copper
Now I am going totally nuts over: which one is the "cathode" and which is the "anode"
I thought the copper would be the anode but then why is the acidic side on the carbon rod and why is the carbon connected to the red wire for this to happen?
I would be so grateful if anyone could help a little on the how and the why. I know this is probably very basic stuff but please don't be rude.
Thank you in any case....
