Question

difference between cathode and anode.

Answer 1

⚫ Anode

♦ The electrode connected to the positive terminal of the battery.

♦ Current enters the electrolyte through the anode.

♦ Anions migrate and discharge at the anode.

⚫ Cathode

♦ The electrode connected to the negative terminal of the battery.

♦ The battery current leave the electrolyte through the cathode.

♦ Cations migrate and discharge at the cathode

Answer 2

Anode is the terminal where the (conventional) current flows into a device from outside. This means that electrons flow out of the device at the anode.

Cathode is the terminal where the (conventional) current flows out of a device. This means that electrons flow into this terminal from the outside.
