When electric current passes through the acidified water, the cation moves towards the positive electrode and anion moves towards the negative electrode. Oxygen is produced at anode and hydrogen is produced at cathode. Describe this process in detail, including the oxidation reaction and overall reaction.
Understand the Problem
The question discusses the process of electrolysis of water, detailing the movement of ions towards electrodes, and the overall chemical reactions that occur during electrolysis. It requires an understanding of basic chemistry concepts related to oxidation-reduction reactions.
Answer
Electrolysis splits water into H₂ and O₂, with oxidation at the anode and reduction at the cathode.
The process of electrolysis involves passing an electric current through acidified water, causing the cation to move towards the cathode and anion towards the anode. Oxygen is produced at the anode through oxidation, and hydrogen is produced at the cathode through reduction.
Answer for screen readers
The process of electrolysis involves passing an electric current through acidified water, causing the cation to move towards the cathode and anion towards the anode. Oxygen is produced at the anode through oxidation, and hydrogen is produced at the cathode through reduction.
More Information
Water electrolysis is a fundamental process in both chemistry and future hydrogen fuel production technologies.
Tips
A common mistake is confusing the direction of movement for cations and anions or mixing up which reaction occurs at each electrode.
