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

The main difference between anode and cathode is that, in general, anode is the terminal where the (conventional) current flows into a device from outside, whereas cathode is the terminal where (conventional) current flows out of the device.
