Question

What is the Difference between cathode and anode?​

Answer 1

#Anode

➡The anode of a device is the terminal where current flows in from outside.

➡In a galvanic cell, the anode is the electrode at which the oxidation reaction takes place or occurs.

➡Oxidation takes place at the anode and where electrons are lost, and

▶ reduction takes place at the cathode where the electrons are gained.

➡The anode is taken to be positive while the cathode is Now as negative.

#Cathode

➡A cathode is known as the electrode from which a conventional current leaves a polarized electrical device.

➡In a galvanic (voltaic) cell, the anode is considered negative(-) and the cathode is considered positive(+).

➡Electrons always flow from the anode to the cathode .

OR

▶ from the oxidation half cell to the reduction half cell.

➡The cathode of a device is the terminal where current flows out.

Answer 2

Negatively charged ions, called anions, move towards the positively charged anode, while positively charged ions, called cations, move towards the positively charged cathode

Electrons always flow from the anode to the cathode or from the oxidation half cell to the reduction half cell.
