Question
What are cathodes and anodes?
Answer
Cathode: The cathode is the electrode in an electrochemical cell or circuit that is connected to the negative terminal of a power source. It is the electrode where reduction takes place during electrolysis or where oxidation takes place during galvanic cell reactions.
Anode: The anode is the electrode in an electrochemical cell or circuit that is connected to the positive terminal of a power source. It is the electrode where oxidation takes place during electrolysis or where reduction takes place during galvanic cell reactions.
