Anode

Postby haileyramsey-1c » Thu Feb 20, 2020 9:18 am

I was wondering why the anode is negative when oxidation is occurring there meaning the reaction is losing electrons which would make it more positive?

The electrons flow from the anode to the cathode. Therefore, the cathode must have a positive charge to attract the electrons, and thus the anode must have a negative charge so that the electrons are not attracted to it.

The Anode must be negative because electrons from the anode flow to the cathode and for this to continue to happen the anode must remain negative. This is made possible from the salt bridge that allows the charge difference to remain constant.

To clarify, the cathode has a positive potential so relative to the cathode, the anode is negative.

Since the electrons flow from the anode to the cathode, the cathode has a positive charge to attract the electrons, and the anode has to stay negative. The salt bridge lets this happen.

So does that mean that the negative ions from the salt bridge go to the anode and the positive ions from the salt bridge go to the cathode to keep the charges the same?
