Question

Electrolysis hydrocloric acid and both of the electrode uses a platinium electrode... what will happen to both of the electrode?​

Answer 1

In the electrolysis of hydrochloric acid using platinum electrodes, the anode will release chlorine gas, and the cathode will release hydrogen gas.

Step-by-step explanation:

In the electrolysis of hydrochloric acid, both electrodes (anode and cathode) will be made of platinum. When current is passed through the hydrochloric acid solution, at the anode, chloride ions (Cl-) will be oxidized to form chlorine gas (Cl2), and at the cathode, hydrogen ions (H+) will be reduced to form hydrogen gas (H2). Therefore, the platinum anode will release chlorine gas, and the platinum cathode will release hydrogen gas.

Answer 2

Hydrogen gas is evolved at the cathode and chlorine gas at the anode.

Step-by-step explanation:

The solution will ionise. Hydrogen ions, H+, will migrate to the negative cathode ( where the current leaves the solution and chloride ions Cl- will migrate the the positive anode.
