Question

What happens to deposition of hydrogen and oxygen during electrolysis when electrodes are reversed

Answer 1

Answer:

they will go to the positive and negative charged electrodes respectively

Explanation:

Answer 2

$2H_2O + electrical energy (+ heat energy)$ → $O_2 + 2H$

Explanation:

Electrolysis of water - water decomposition or breaking of water molecules evolving hydrogen and oxygen gases carried out under the influence of an electric current.

$2H_2O + electrical energy (+ heat energy)$ → $O_2 + 2H$

• During Electrolysis an electric potential is passed through water
• This potential initiates the ions to move towards respective electrodes in accordance with the charge
• Positive ions tend to move towards the negative electrode (cathode)
• Negative ions tend to move towards the positive electrode (anode)
• The potential difference created causes electrolysis that makes the oxygen gas to be deposited at the anode and hydrogen gas to be deposited at the cathode
• If the electrodes are reversed the deposition of gases will also be reversed
