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

➡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 electrons are gained.

➡The anode is taken to be positive while the cathode is now 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.
