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

Cathode is negatively charged electrode and anode is positively charged eletrode the ions that move towards cathode are positively charged and are called cations and the ones that move towards anode are called anions.

The cathode is negatively charged and all the positively charged cations move towards it and accept electron to deposit as neutral atoms on the cathode .

Anode donates electrons meaning it releases charged ions which decreases the size of the anode this causes flow of electron from anode to cathode and maintains an electric current.
